The the exact circumference of a circle with the given radius is 200.96.
Step-by-step explanation:
Here, the radius of the given circle = 32 cm
The, Circumference of a Circle = 2 π r
So, here C = 2 x 3.14 x 32 (taking π = 3.14)
or C = 200.96
Hence, the the exact circumference of a circle with the given radius is 200.96.
