Question

The circumference of a circle is about 50 centimeters
(cm). What is an estimate of the length of its radius?
3.14 for pie.

Answer 1

Answer:

r is about 8 cm

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

50 = 2 * 3.14 *r

50 = 6.28r

Divide each side by 6.28

50/6.28 = 6.28r/6.28

7.961783439 = r

r is about 8 cm
