Question

Find the area and the circumference of a circle with diameter 10 m.

Write your answers in terms of pi, and be sure to include the correct units in your answers.

Answer 1

Explanation:

area of a circle= πr²

and r= half diameter

therefore we have r=10/2=5

area= 5² x π

area= 25π

circumference=2πr

circumference= 2xπx5

circumference=10π
