Question

The area of a circle is 452.39 ft^2 . Why would the diameter have to be?

Answer 1

I believe it would be 24ft.

Answer 2

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! :)
