Question

find the radius of a circular sheet whose perimeter 132 m. also, find its area.
($\pi = \frac{22}{7}$)

Answer 1

Step-by-step explanation:

For a circle

perimeter = circumference = 2πr

132 = 2πr

66 = 22/7 r

r = 21 cm

Area = πr^2

= 22/7 ×21×21

= 1386 sq cm

Answer 2

Answer:

2πr

2*22/7+r=132

44/7+r=132

r=132*7/44

r=3*7(132 get divided by 44)

r=21
