The circumference of a circle is about 50 centimeters

(cm). What is an estimate of the length of its radius?

3.14 for pie.

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
