If the area=14 pi cm squared, find circumference and diameter in terms of pi

Hi Sam Fisha, formula for area is pi r^2
Given pi r^2 = 14 pi cm^2
So cancelling pi on both sides, we get r^2 = 14
So r = ./14 cm
Now circumference C = 2 pi r = 2./14 pi cm
Diameter = 2 radius = 2./14 cm
./ stands for square root symbol

Area = pi r ² = 14 pi cm²
==> r² = 14
r = √14
d = 2√14
Circumference = 2 pi r = 2 pi √14 = 2√14 pi

Pi R^2 = 14 Pi
R^2 = 14
Dia = 2(14^-1)
Cic. = Pi[2(14^-1)}

A=πr^2
C=2πr
r^2=d

A=14π
√14=r

C=2π√14
C=[2√14]π

√14^2=14
D=14

Hope this helps!
