Question

circumference of a circle =220. find its radius

Answer 1

Answer:

8.36 cm

Step-by-step explanation:

Circumference of circle = 220 cm

πr^2 = 220

22/7 × r^2 = 220

22 × r^2 = 220 × 7

22 × r^2 = 220 × 7 22 × r^2 = 1540

πr^2 = 220 22/7 × r^2 = 220 22 × r^2 = 220 × 7 22 × r^2 = 1540r^2 = 1540 / 22

πr^2 = 220 22/7 × r^2 = 220 22 × r^2 = 220 × 7 22 × r^2 = 1540r^2 = 1540 / 22 r^2 = 70

πr^2 = 220 22/7 × r^2 = 220 22 × r^2 = 220 × 7 22 × r^2 = 1540r^2 = 1540 / 22 r^2 = 70 r = √ 70

πr^2 = 220 22/7 × r^2 = 220 22 × r^2 = 220 × 7 22 × r^2 = 1540r^2 = 1540 / 22 r^2 = 70 r = √ 70 r = 8.36 cm
