Circumference of a circle is 33 cm. Find its area.

Solution:

Consider r as the radius of circle

2πr = 33

r = 33/2π

By further calculation

r = 33/2 × 7/22

r = 21/4

So the radius is 21/4 cm

We know that

Area of circle = πr²

Substituting the values

= 22/7 × 21/4 × 21/4

= 693/8 cm²

Therefore, the area of the circle is 693/8 cm².
