Question

1. Find the radius of a circle whose area is 12474 cm²​

Answer 1

Answer:

Step-by-step explanation:

area of circle = πr^2 = 12474 cm^2

22/7 × r^2 = 12474

r^2 = 12474 ×7/22

r = √3969

r = 63

Hence radius = 63 cm

Answer 2

Answer:

63

Step-by-step explanation:

area of circle=124747 sq cm

πr^2 = 12474

22/7 r^2 =12474

r^2 = 12474×7/22

r^2 = 6237×7/11

r^2 = 43659/11

r^2 = 396

r =√3969

r=63
