Question

A circle has a diameter of 30 yd. What is it’s circumference?

Use 3.14 for PIE, and don’t your answer.

Answer 1

Circumference of the circle = 94.2 yd

Solution:

Given data:

Diameter of the circle = 30 yd

The value of π = 3.14

To find the circumference of the circle:

Circumference of the circle = πd

Substitute the diameter value in the formula, we get

Circumference of the circle = 3.14 × 30

                                              = 94.2

Circumference of the circle = 94.2 yd
