Answer: 18 units


Explanation:

Area = π r²

1017.9 =  π r²

r² = 1017.9 ÷ π

r² = 324

r = √324

r = 18

===> Radius = 18 units
your radius is 18.

use a = pi time radius squared

divide your area by pi

since your answer is squared, you want to unsquare it.

you have to find the square root of your number, then that'll be your answer.

hope this helped.
