Find the radius of a circle whose circumference is 56.52 cm
Realagent:
Use formula r= c/2π
r = c/2pi is came from c= 2 x pi x r
as u keep ' r ' in right side 'pi' and '2' will b in the denominator of c.

Step-by-step explanation:
2 * pi * r = 56.52
2*22/7 * r = 56.52
r = 56.52*7/22*2 = 8.99 cm (approx.)

Answer:
Step-by-step explanation:
circumference of a circle = 2 π r = 56.52 cm
2 π r = 56.52
2 x 22/7 x r = 56.52
2 x 22 x r = 56.52 x7
44 r = 395.64
r = 395.64 / 44
r = 8.99 cm
