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.

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

The radius of the circle is 63 meters

Step-by-step explanation:

circumference of a circle is given by the formula C=2πr

It is given that,

circumference is 396 meters

To find the radius of circle

C=2πr         π= 22/7     C = 396

2*(22/7)*r  = 396

r = (396 * 7)/(2*22)

r = 63

Therefore the radius of given circle = 63 meters.

-14 is the answer

hope this : ))

i do not know this sorry : (
