Question

Find the area of a concrete path 2m wife surrounding a circular pond 12m in diameter

Answer 1

Answer:

$\text{Area of the concrete path is }88\,m^2$

Step-by-step explanation:

$\text{Given:}$

$\text{Diameter of circular pond is 12 m}$

$\text{Then, its radius is r=6 m}$

$\implies\text{Radius of outer circle R=8 m}$

$\textbf{Area of the concrete path=Area of the outer circle-Area of the inner circle}$

$\text{Area of the concrete path}$

$=\pi(R^2-r^2)$

$=\frac{22}{7}(8^2-6^2)$

$=\frac{22}{7}(64-36)$

$=\frac{22}{7}(28)$

$=(22)(4)$

$=88\,m^2$

$\therefore\textbf{Area of the concrete path is }88\,m^2$
