Question

if the perimeter of circle is 44 cm,then its area?

Answer 1

Answer:

Step-by-step explanation:

Let r be the radius of the circle

Perimeter of circle = 44cm

2πr = 44

2 * 22/7 * r = 44

(Transporting numerical values to RHS)

r = (44 * 7)/(2*22)

r = 308 / 44

r = 7cm

Now, Area of circle = πr sq.

Area = 22/7 * 7 * 7

Area = 154cm sq.

Hence, Area of the circle = 154 cm sq.
