Question

find radius if area is 154sq cm

Answer 1

Area of a circle A=πr2 , where r is the radius. Given A=154 , ⇒154=π⋅r2 ⇒r2= 154π=49.02. ⇒r=√49.02=7.00. Was this helpful

Answer 2

Heya friend,

Given that

Area of a circle = 154 sq. cm

Solution

Let the radius of a circle be r cm. Then,

Area of a circle= πr^2

=> 154 = 22/7 × r^2

=> 154 × 7/22 = r^2

=> 49 = r^2

=> r = √49

=> r = 7cm
