42.8 ft2
113.0 ft2

Answer 1

use the formula :
area = pi * r^2

Answer 2

whats that?

Answer 3

how do you use that formula?

Answer 4

that is the formula to find the area of a circle, with pi=3.14 and r its radius
dont forget the radius of circle always 1/2 of diameter

Answer 5

so what do you times pi with?

Answer 6

from ur pic, given the diameter of circle is 12 ft. so, u have to determine the value of its radius, first.
r = 1/2 * d = 1/2 * 12 = 6
now, apply it to formula above :
Area = pi * r^2 = 3.14 * 6^2 = 3.14 * 36 = ......

Answer 7

113.04

Answer 8

yes, i got like u

Answer 9

i have a couple more if you want to help, your like the best that can explain it to me.
