Question

Find the area of a semicircle with the radius is $2$ m. (Use $\pi =3$)

• A. $2$ m${}^2$
• B. $3$ m${}^2$
• C. $5$ m${}^2$
• D. $6$ m${}^2$

Answer 1

The correct option is D $6$ m${}^2$

Area of the semicircle $=$ $\frac{1}{2}\pi r^2$
$=$ $\frac{1}{2}\times 3\times 2^2$
Area of the semicircle $=6$ m${}^2$.
