Question

find the radius of the circle whose circumference is 77 CM

Answer 1

Ans: Circumference of circle = 77
=>2pi r = 77
=>2× 22/7 × r = 77
=> r = 77 × 7 /2 × 22
=> r= 49 /2
=> r= 24.5

Hope it helps...!!

Answer 2

_______Heya!!__________


Given:-

Circumference of the circle=77cm

As we know that,

Circumference of the circle = 2πr

=>77cm = 2πr

=>77cm = 2 ×22/7×r

=>77 ×7/2×22= r

=> r =12.25 cm


radius of the circle=
