Problem

Rachel is building a circular pond in her garden. The radius of the pond is 5 meters. Find the area of the pond.(Use π = 3.14)

Hint

Formula used

\$"Area(A)" = \pi \times r^2\$

Step

Given that,

Radius(r) of the pond =

r = 5 m

Step

Area of the pond =

\$\pi \times r^2\$

⇒ \$\pi \times 5^2\$

⇒ \$\pi \times 25\$

⇒ \$(3.14) \times 25\$

⇒ \$78.5 m^2\$

Step

Hence, the area of circular pond is

\$78.5 m^2\$
