A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Answer:
Lateral Surface Area = 94.25 cm²
Surface area = 150.8 cm²
Step-by-step explanation:
A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Step 1
We have to find the radius of the cylinder
We are told in the question that:
The circumference of one circle is 18.84 cm
Circumference of a circle = 2πr
18.84cm = 2πr
r = 18.84/2π
r = 2.9984791279cm
Approximately the radius = 3cm
Step 2
We find the Lateral Surface Area of the Cylinder
The formula =2πrh
r = 3cm
h = 5cm
=2×π × 3 × 5
= 94.24778 cm²
Approximately = 94.25 cm²
Step 3
We find the Surface Area of the Cylinder
The formula =2πr(r + h)
r = 3cm
h = 5cm
=2×π × 3 × 5(3 + 5)
= 150.79645 cm²
Approximately = 150.80 cm²

Of the players on a bowling team7/10 or 7 won trophies. Explain how you can find the number of players on the team.?
Answer:
10players
Step-by-step explanation:
Using the concept of probability
probability = expected outcome/total outcome
Total outcome s the numbers of players on the team
Given
Total number of trophy won = 7 (expected)
Fraction of those that won = 7/10 (probability)
Substitute
7/10 = 7/total outcome
1/10 = 1/total outcome
Reciprocate both sides
10/1 = total outcome
Swap
Total outcome = 10
Hence the number of players on the team is 10players

Alek and Ann start walking around a track at the same time and at the same place. It takes Ann 6 minutes to walk around the track, and it takes Alek 8 minutes. After how many minutes will they reach the starting point at the same time
Answer:
3 3/7 minutes
Step-by-step explanation:
This calculated using the formula:
1/x + 1/y = 1/n
Where
x = Number of minutes it took Ann to walk = 6 minutes
y = Number of minutes it took Alek to walk = 8 minutes
n = Number of minutes it would take An and Alek to reach the starting point at the same time
1/6 + 1/8 = 1/n
Lowest Common Denominator = 24
4 + 3/24 = 1/n
7/24 = 1/n
Cross Multiply
7n = 24
n = 24/7
n = 3 3/7 minutes
It would take them 3 3/7 minutes to reach the starting point at the same time.
which of the expressions have a value of 2?
Answer:
The answers are B and E
Step-by-step explanation:
The square root of 4 is 2.
The cube root of 8 is 2.
A is wrong because its value is 4.
C is wrong because its value is 4.
D is wrong because the square root of 8 isn't whole.
Answer:
E. √4
B. ³√8
Step-by-step explanation:
You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)
You can also determine that B is correct by doing 2 to the power of 3.
2³ = 8, so you know that B is correct too.

1. When Aaron runs the 400 meter dash, his finishing times are normally distributed with a mean of 80 seconds and a standard deviation of 2.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 99.7% of his finishing times in the 400 meter race.
Answer:
(72.5,87.5)
Step-by-step explanation:
The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)
What is the interval from empirical rule?
We are given;
Mean; E(X) = μ = 80 seconds
Standard Deviation; σ = 2.5
From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.
We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;
μ - 3σ = 80 - 3(2.5) = 73.5
μ + 3σ = 80 + 3(2.5) = 87.5

If a_n is a sequence that includes the terms:
250, ___, 10
What missing number(s) would the missing term be if:
a) a_n is arithmetic
b) a_n is geometric
9514 1404 393
Answer:
arithmetic: 130geometric: ±50Step-by-step explanation:
Arithmetic sequence
The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:
x -250 = 10 -x
2x = 260 . . . . . . add 250+x to both sides
x = 130 . . . . . . . . divide by 2
The missing term of an arithmetic sequence is 130.
(the common difference is -120)
__
Geometric sequence
The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:
x/250 = 10/x
x^2 = 2500 . . . . . . . multiply both sides by 250x
x = ±√2500 = ±50 . . . take the square root
The missing term of a geometric sequence is +50 or -50.
(the common ratio is ±1/5)

Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)
Mr. Pope decreased his weight by 4 percent.
What is percentage?A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.
Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.
we need to find the percentage of decrease of his weight,
So, basically we will use here the concept of percentage change,
Formula = final amount - initial amount / initial amount x 100
Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds
So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]
Hence, Mr. Pope decreased his weight by 4 percent.
