Question

What is the circumference of circle P?

Express your answer in terms of Pi

PB= 29 m

Answer 1

The formula for circumference: 2rpi

PB = r = 29m

The circumference of circle P is:

2(29)pi

=58pi

Answer 2

The circumference of circle =58π m

Explanation:

Points to remember

Circumference of circle = 2πr

Where r is the radius of the circle

From the figure we can see a circle with radius PB = 29 m

To find the circumference of circle

Here r = 29 m

Circumference = 2πr

= 2 * π * 29

= 58π m

Therefore the circumference of circle =58π m
