Question

Area of a circle is 616 CM square find the diameter of a circle

Answer 1

Answer:

diameter = 28 cm

Step-by-step explanation:

Given:- area of circle = 616 cm²

we know that,

area of circle = πr²

so, πr² = 616 cm²

22/7 × r² = 616 cm²

22 × r² = 616 × 7

22 × r² = 4312 cm²

r² = 4312/22 cm²

r² = 2156/11 cm²

r² = 196 cm²

r = √196 cm

r = 14 cm

so, we know that diameter of circle is the doubled of the radius of the circle.

diameter = 2 × radius

diameter = 2 × 14 cm

diameter = 28 cm

therefore, the diameter of a circle is 28 cm.
