Question

The circumference c of a circle is given by the formula c equal 2 pi if the radius of the circle is 10 inches find the circumference of the circle

Answer 1

62.8 inches

Explanation:

c = 2πr

Where,

c = Circumference of a circle

π = pi = 3.14

r = radius = 10 inches

c = 2πr

= 2 × 3.14 × 10

= 62.8 inches

c = 62.8 inches

Therefore,

The circumference of the circle is 62.8 inches
