Question

IF U ANSWER THE QUESTION I WILL MARK U AS BRAINLIEST The perimeter of a semicircle is 72 cm find its area​

Answer 1

Step-by-step explanation:

Let r be the radius of the semi-circular protractor

Then the perimeter of the protractor is (πr+2r)=736r

According to the problem

736r=72

r=14

Now area of the protractor is

2πr2=711×14×14

=22×14=308cm2

hope it helps pls mark as brainliest

Answer 2

Answer:

308cm^2

Step-by-step explanation:

Perimeter =pie *r+2r

= 22/7*r+2*r=72

= 36/7r=72

r= 72*7/36=14

Area = pie *r*r/2

22/7*14*14/2=308
