πr^2=16π
r^2=16
r=4
2πr =perimeter
2(4)*π
=8π
r^2=16
r=4
2πr =perimeter
2(4)*π
=8π

Area of the given circle = 16 pie
area of a circle= pie r^2
so, 16 pie= pie r^2
16=r^2
r=4 units.
Perimeter= 2 pie r
= 2 x pie x 4 = 8 pie
area of a circle= pie r^2
so, 16 pie= pie r^2
16=r^2
r=4 units.
Perimeter= 2 pie r
= 2 x pie x 4 = 8 pie
