Question

Circle O has a circumference of 887 cm. What is the length of the radius of the circle? cm

Answer 1

Answer:

44cm

Step-by-step explanation:

Formula for circumference, C = 2πr

where r is the radius

r = C / 2π

= $\frac{88\pi }{2\pi }$

=44 cm

Answer 2

Answer:

approximately 44 cm

Step-by-step 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
