Question

Find the radius of semicircle whose area is 2464cm?.​

Answer 1

Answer:

Given: The area of the semicircle is 2464 cm².

To find : The radius of the circle.

Solution :

The area of the semicircle is defined as

A = (πr²)/2

Where, A=2464 cm² is the area,

r is the radius

Substituting the values,

2464 = (22/7 × r²)/2

2464 × 7/22 = r²/2

r² = 784 × 2

r² = 1568

r = √1568

r = 39.59 cm
