Step-by-step explanation:
can somebody explain how to get the answer/ what formula, and the answer??
Answer:
9 cm
Step-by-step explanation:
divide the total circle centimeter which is 18 in half. Half of 18 is 9 so the diameter is 9.
Answer:
R = 9 cm
Step-by-step explanation:
C = 2ПR
Also C = 18П сm
2ПR = 18П
R = 18П/2П = 9 сm

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
area: about ???
mm2
9514 1404 393
Answer:
2463.01 mm²
2461.76 mm² if you use 3.14 for π
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
where r is the radius, half the diameter.
For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...
A = π(28 mm)² = 784π mm²
For an appropriate value of π, the area is ...
784π mm² = 2463.00864... mm² ≈ 2463.01 mm²
For 3.14 as the value of π, the area is ...
784(3.14) mm² = 2461.76 mm²
_____
Comment on pi
Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.
Please answer all parts of this ASAP.

Jada has 12 library books checked out and Han has LaTeX: \frac{1}{3}1 3 less than that. How many books does Han have checked out?
Answer:
8
Step-by-step explanation:
The questions is difficult to read but if it means "Jada has 12 library books checked out and Han has 1/3 less than that" Han would have 8 because 12/3 is 4. 12-4 is 8. This would only be correct if that is what the problem means. Sorry. I'm not sure what "LaTeX: \frac{1}{3}1 3" means.
Lucy wants to buy a basketball that costs $30. She lives in a state that has 10% sales tax. What is the final price she will pay for the basketball including tax?
Answer:
I think 33 dollars
Step-by-step explanation:
Cost of the ball= $30
Sales tax= 10 %
Amount to be paid as tax = 10/100 x 30 = $3
Final price = MP + Tax = 30 + 3 = $33
Which of the following is equivalent to 5:4? *
25:15
20:19
30:20
10:8
15:16
100:85
Answer:
10:8
Step-by-step explanation:
5*2=10
4*2=8
10:8
Answer:
the answers equivalent to 5:4 is 10:8
Step-by-step explanation:
The reason I only chose 10:8 is because all the other answers are not even multiples of 5 or 4 or they were multiples of 5 and 4 but they were not multiplied by the same number.
Example:
25:15 = okay so 5 can go into 25, 5 times but 4 cannot go into 15
20:19 = okay so 5 can go into 20, 4 times but 4 cannot go into 19
30:20 = though 5 can go into 30 and 4 into 20 they are not multiplied by the same number
15:16 = though 5 can go into 15 and 4 into 16 they are not multiplied by the same number
and last but not least 100:85 = okay so 5 can go into 100, 20 times but 4 cannot go into 85
So it leaves 10:8= 5 can go into 10, 2 times and 4 can go into 8, 2 times so this is your answer.
Hope this helps you!!!
5 * 2 = 10 and 4 * 2 = 8

Estelle drew two parallel lines, PQ and RS, intersected by a transversal KL, as shown below: Two parallel lines, PQ and RS, are drawn with KL as a transversal intersecting PQ at point M and RS at point N. Angle KMQ is shown congruent to angle MNS. Which fact would help Estelle prove the measure of angle KMQ is equal to the measure of angle MNS? When both angle KMQ and angle MNS are equal to angle RNM, the angles KMQ and MNS are congruent. When same-side, consecutive interior angles QMN and PMN are complementary, the angles KMQ and MNS are congruent. When alternate interior angles QMN and MNR are supplementary, angles KMQ and MNS are congruent. When both angles KMQ and MNS are equal to angle PMN, the angles KMQ and MNS are congruent.
Answer:
I'm pretty sure the answer is d,(When both angle KMQ and MNS are equal to angle PMN, the angles KMQ and MNS are congruent.)

If the diameter of a circle is 12, what is the area and circumference?
Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
Answer:
circumference = 37.68 (37.7 if you're rounding it)
Area = 113.04 (113.1 if you're rounding it)
Step-by-step explanation:
The formula for circumference is C=2πr (2 times pi times radius)
If the diameter is 12, the radius is 6.
2 x 3.14 x 6 = 37.7
The formula for area is A=πr2 (pi x radius to the second power)
The radius is 6. Six to the second power is 36.
36 x 3.14 = 113.04

We need to find which of the following are rational numbers.
What is a rational number?The numbers that can be written in the form of p/q where q ≠ 0 are called rational numbers.
Rational numbers are terminating and recurring numbers.
Example: 2, 1/4 = 0.25, 1.333333333
Check the following numbers.
- 5/6
= 0.8333333
we see that 3 is repeating.
It is recurring so it is a rational number.
- √π
= 22/7
= 3.1428571...
It is non-terminating so it is not a rational number.
- 6.565656...
We see that 56 is repeating.
It is recurring so it is a rational number.
- 0.23
It is terminating.
It is a rational number.
- 0.32416....
It is non-terminating so it is not a rational number.
-5 3/8
= 43/8
=5.375
It is terminating.
It is a rational number.
Thus 5/6, 6.565656.., 0.23, -5 3/8 are rational numbers.
