Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.

area: about ???

Answers

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.

I WILL GIVE BRAINLIEST! DO NOT ANWSER IF YOU DON'T KNOW! Guy and Jim work at a furniture store . Guy is paid $185 per week plus 3% of his total sales, in dollars, x, which can be represented by g(x) = 185 + 0.03x. Jim is paid $275 per week plus 2.5 % of his totals sales in dollars, x, which can be represented by j(x) = 275 + 0.025 x . Determine the value of x, in dollars, that will make their weekly pay the same.

Answers

Answer:

185 + 0.03x = 275 + 0.025x

Step-by-step explanation:

0.03x - 0.025x = 275 - 185

0.005x = 90

Divide both sides by 0.005

x = 90/0.005

x=18000

Solve:
7/8 - (-1/8)
A. -1
B. -1/8
C. 1/8
D.1

Answers

D, because two negative signs next to each other means to add so its pretty much 7/8+1/8 which equals 8/8 which also equals 1

Subtracting a negative is the same as adding a positive, since the negatives cancel each other out.

So, 7/8 - (-1/8) is the same as 7/8 + 1/8. Adding 1/8 to 7/8 gives you 8/8, or one whole, so your answer is D. 1!

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?

Answers

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

To solve anything for tax, you can do it in one step, or 2 steps. To solve it in one step, simply put the tax amount into a decimal, with a one in front. So for this question, you would put 1.10 and multiply by the amount. So 30x1.10=$33. Or you can just multiply 30 by a decimal with a 0. So 0.10x30=3. Then add the 3 to 30

If the diameter of a circle is 12, what is the area and circumference?

Answers

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

Answers

Answer:

( I am assuming that these are all fractions)

1. 14 [tex]\frac{4}{7}[/tex]

2.  8

3. [tex]\frac{4}{15}[/tex]

4. 5 [tex]\frac{8}{11}[/tex]

Step-by-step explanation:

1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]

2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8

3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .

4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]
