Question

What is the circumference of a circle which has 14 ft as diameter?

Answer 1

Circumference of circle = 2πr = πd

                                       = 22/7 × 14 ft

                                       = 44 ft.

Answer 2

Given,

Diameter of the circle = 14 ft.

To Find,

The circumference of the circle.

Solution,

To calculate the circumference of the circle, we need to calculate the radius of the circle.

Radius = diameter/2 = 14/2 = 7 ft.

Now,

circumference of the circle = 2πr

circumference of the circle = 2*22/7*7

circumference of the circle = 44 ft.

Hence the circumference of the circle is 44 ft.
