Question

Circle O has a circumference of 887 cm.

What is the length of the radius of the circle?
cm

Answer 1

approximately 44 cm

Explanation:

The formula for circumference of a circle of radius r is C = 2π·r. Solving for r, we get:

C

r = ------------

2π

and in this instance, r = 88π cm / 2π, or 44 cm

Answer 2

44cm

Explanation:

Formula for circumference, C = 2πr

where r is the radius

r = C / 2π

=
`(88\pi )/(2\pi )`

=44 cm
