Question

The area of a circle is 154cm . Find the radius of the circle

Answer 1

Answer:

7 cm

Step-by-step explanation:

area of circle = π r²

154 = 22/ 7 × r²

r² = 154 × 7 / 22

r² = 7 × 7

r = √49

r = 7 cm

Answer 2

Given,

Area of circle = 154 cm^2

To find : Radius of circle r.

We know,

Area of circle = πr²

154  = 22/7 * r²

r² = 154 * 7 / 22

r = √49

or, r = 7 cm
