Question

Find the area and the circumference of a circle with radius 6 m.

Write your answers in terms of it, and be sure to include the correct units in your answers.
(a) Area:
6 m
(b) Circumference:

Answer 1

Explanation:

(a) πr^2= 22/7 * 6*6

= 113.1 m^ 2

(b) 2πr= 2*22/7*6

= 37.7 m

Answer 2

(a) 113.04m²

(b) 37.68m

Explanation:

(a)

Area = πr²

=π(6)²

=36π

=113.04m²

(b)

Circumference = 2πr

2π(6) = 12π

=37.68m
