Answer 1

Question

Find the area of semi circle whose diameter is 14m?

Solution

________________

Diameter= 14m

Therefore,

Radius=r= (14/2)m=7m

_____________

Area of semi circle= (1/2)πr^2

___________________

There, by applying that formula,

There, by applying that formula,we get

$= \frac{1}{2} \times \pi \times {7}^{2} \\ = \frac{1}{2} \times 49 \times \frac{22}{7} \\ = 49 \times 11 \times \frac{1}{7} \\ = 7 \times 11 \\ = 77$

________________________

There, area of the semi-circle is 77sq.m
