Given, d = 14cm then the radius r will be 7 cm.

We know that Area of a semicircle = 1/2 * pi * r * r

                                                           = 1/2 * pi * 7 * 7

                                                           = 1/2 * 22/7 * 7 * 7
 
                                                          = 77 cm^2.


Hope this helps!

Answer:

area of a semi circle = 1/2πr^2

diameter= 14cm

ie;radius =14/2=7

lets give the value of π= 22/7

therefore, 1/2 ×22/7×7×7

by solving this we get 154/2

that is 77cm^2

Thank you
