Question

How do u find the circumference of a circle and the radius of a circle?

Answer 1

Answer: radius=8, circumference=16π

Explanation:

diameter is 16 centimeters

the radius of a circle is half its diameter

so, radius = 16/2 = 8

circumference of a circle = 2πr

so, circumference = 2π(8cm) = (16π) cm
