Question

What is the exact circumference of a circle with a radius of 45 cm?

HELP ASAP!!!

Answer 1

Lets get started :)

The circumference formula of a circle is
C = 2
`\pi`r (r being the radius)

If radius = 45, substitute 45 instead of r

C = 2
`\pi`(45)
=90
`\pi`
≈ 282.7433388

I suppose you leave it in the pi (
`\pi`) form

Answer 2

The answer is 282.7433
