Question

How is the area of a semicircle found?

Answer 1

Answer:

(A) Take half the area of the whole circle.

Step-by-step explanation:

A semi-circle is half of a circle, thus the area of circle is given by:'

Area of circle=${\pi}r^2$, where r is the radius of the circle.

Since, A semi-circle is half of a circle, therefore area of the semi circle is also half of the circle, therefore

Area of semi circle=$\frac{{\pi}r^{2}}{2}$

Thus, the area of the semi circle can be found by taking half the area of the whole circle.
