Question

The radius of a circl that is 15.4cmsquared

Answer 1

Area of the circle = 15.4cm²

Formula of area of circle = πr²

πr² = 15.4 cm²

22/7×r² = 15.4

r² = 15.4×7/22

r² = 107.8/22

r = √4.9

r = 2.21 cm(approx.)

Radius of the circle = 2.21 cm

Here is your answer and hope it will help you.
