Question

Find the surface area of a circular shaped pool whose diameter is 28 m (Use π = \(\frac {22}7\))

Answer 1

The diameter of circular shaped pool (d) = 28 m

Radius (r) = \(\frac {28}7\) m = 14 m

Area of a circular shaped pool = πr²

=\(\frac {22}7\) × (14m)²

=\(\frac {22}7\) × 14m × 14 m

= 22 × 2 × 14 sq.m. 

= 616 sq.m.
