The circumference of a circle is given by the formula C=2πr. Find r if the circumference is 396 meters and π is 22/7.
larisa86 [58]

Answer:

r = 63 meters

Step-by-step explanation:

C=2πr

We know pi and C

396 =  2*22/7*r

396 = 44/7 *r

Multiply each side by 7/44 to isolate r

396*7/44 = 7/44 *44/7 *r

63 =r
