Question

A circle with diameter $8cm$ is divided into $18$ equal parts as shown. Find the area of one region among the $18$ equal parts. (Take $\pi =3.14)$

• A. $2.791c{m}^2$
• B. $5.024c{m}^2$
• C. $1.432c{m}^2$
• D. $3.836c{m}^2$

Answer 1

The correct option is A $2.791c{m}^2$

Area of circle $=\pi r^2=3.14\times 4\times 4=50.24{cm}^2$

$\therefore$ Area of each part $=\frac{50.24}{18}=2.791{cm}^2$
