Question

Circle O has a circumference of 88π cm.

Answer 1

Answer:

44 cm

Step-by-step explanation:

The circumference formula is:

C = 2πr

We are given the circumference of circle O, so we substitute C with the given circumference and solve for r.

88π cm = 2πr

Switch sides:

2πr = 88π cm

Divide both sides by 2π:

$r = \dfrac{88\pi}{2\pi} cm$

r = 44 cm

Answer 2

The radius is 44 cm long
