Question

the area of a semicircle is 308mtr² then find the radius of circle​

Answer 1

Answer:

radius = 35.6 m

Step-by-step explanation:

Given that,

Area of a semicircle is 308 m².

We know that,

Area of a semicircle = ¹/₂ (πr²)

∴ 308 = ¹/₂(πr²)

∴ 616 = πr²

Putting π = 22/7

∴ 616 = 22/7*r

616 * 7/22 = r

56 * 7/11 = r

392/11 = r

35.6 = r

∴ r = 35.6 m
