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
