No 5 a. 22/7 x r^2 = 44 r^2 = 44 x 7/22 r^2 = 2 x 7 r^2 = 14 r = √ 14 b. 22/7 x r^2 = 154 r^2 = 154 x 7/22 r^2 = 7 x 7 r = 7 c. r^2 x 22/7 = 2464 r^2 = 2464 x 7/22 = 112 x 7 = 784 r = √ 784 = 28
a. 22/7 x r^2 = 44
r^2 = 44 x 7/22
r^2 = 2 x 7
r^2 = 14
r = √ 14
b. 22/7 x r^2 = 154
r^2 = 154 x 7/22
r^2 = 7 x 7
r = 7
c. r^2 x 22/7 = 2464
r^2 = 2464 x 7/22 = 112 x 7 = 784
r = √ 784 = 28
