Question

PLEASE HELP!!

a circular playground has an area of 1600 square feet if the committee decides to double the radius what will the area of the new playground be

Answer 1

C

Step-by-step explanation:

Just did the quiz with a 100%

Answer 2

Answer: C

Explanation:

Since the radius of a circular playground with 1600 square feet is 22.568, doubling the radius will get you 45.136. So, we can input each choice into the formula for the radius of a circle:

r=
`\sqrt{(A)/(\pi )`

Through process of elimination, we can see that only a circle with an area of
`6400ft^(2)` will give us the radius of 45.136.

Sorry for not being as explicit I was rushing a bit. Hope this helps though uwu!
