Answer:
(a)77 cm^2
Step-by-step explanation:
Given: radius, r = 7 cm
Clearly, from the above picture, the figure is a semi circle. We know the area of the circle, I.e.,
Area of the circle = πr^2
Area of the semi circle is half of the area of the circle,
Area of semi circle = 1/2πr^2
= 1/2 x 22/7 x 7 x 7
= 11 x 7
= 77 cm^2
Your answer : (a) 77 cm^2
