formula for circumference is c= 2 (pi)r

62.8 = 2 (3.14)r
62.8 = 6.28 (r)
62.8/6.28 = r
10 = r

Radius is 10 inches
apologiabiology
circumerence=2 times pi times radius
circumference=62.8
62.8=2 times pi times r
divide both sides by 2
31.4=pir
aprox pi to 3.14 and divide both sides by 3.14
10=r

radius= 10in
