Question

Area of circular garden with diameter$8m$is

• A. $12.56m^2$
• B. $25.12m^2$
• C. $50.24m^2$
• D. $200.96m^2$

Answer 1

The correct option is C

$50.24m^2$

Correct option: (c) $50.24m^2$

Explanation

We know that,

Area of circle $=\pi r^2$

Given diameter $=8m$

Then, radius $=\frac{8m}{2}$

Radius $=4m$

So,

$\begin{array}{rcl}Areaofcircle& =& {\mathrm{\pi r}}^2\\ & =& 3.14\times 4\times 4\\ & =& 3.14\times 16\\ & =& 50.24{\mathrm{m}}^2\\ & & \end{array}$

Thus, the area of the circle$=50.24m^2$

Hence, the correct option is (c )
