Question

find the area of the adjoining figure is​

Answer 1

Answer:

c) The area of the adjoining figure is 77 sq. cm.

Step-by-step explanation:

Given figure is the semicircle

Dimeter = 14 cm

radius (r) = 14/2 = 7 cm

If area of circle = $\pi r^2$

Then area of the semicircle = $\frac{1}{2} \pi r^2$

$= \frac{1}{2} \times \frac{22}{7} \times (7)^2\\= \frac{1}{2} \times \frac{22}{7} \times 49\\= \frac{1}{2} \times22 \times 7\\= 11 \times 7\\= 77 cm^2$

So, the area of the given semicircle is 77 sq. cm.
