STEP 1:
Find the radius.

Area=πr^2
plug in the known numbers

452.39= (3.14)r^2
divide both sides by 3.14

452.39 ÷ 3.14= r^2

144.07= r^2
take the square root of 144.07 and r^2

12 feet= r

STEP 2:
multiply radius by 2 to equal diameter

Diameter= Radius * 2
Diameter= 12 feet * 2
Diameter= 24 feet

ANSWER: The diameter would be 24 feet.

Hope this helps! :)

A group of students organized a car wash to raise money for a local charity. The students charged $5.00 for each car they washed

Gala2k [10]

The students will earn $180 by washing cars for 9 hours.

In 3 hours the students will earn...

$5 x 12 = $60

5 dollars x 12 cars = 60 dollars

So in 3 hours the group of students will earn $60

In 9 hours the students will earn...

$60 x 3 = $180

Since the students will earn $60 per every 3 hours, you multiply $60 with 3 because if you divide 9 hours by 3 hours you will get 3. The answer you get by multiplying 60 by 3 is 180. Therefore the students can earn $180 from washing cars.

I hope this helps!
