Question:

If the perimeter of a circle is 88 cm, then what is the area of the circle? ($\pi = \frac{22}{7}$)

Options:

616 m2

566 m2

886 m2

446 m2

Correct Answer:

616 m2

Explanation:

The circumference of the circle = 88 cm

= 2πr = 88

= 2 × \(\frac{22}{7}\) × r = 88

= (\(\frac{44r}{7}\)) = 88

= r = 2 × 7 = 14 cm

We know that,

The area of the circle =  πr2 

\(\frac{22}{7}\)× 142

22 × 28 = 616 m2
