If the perimeter of a circle is 88 cm, then what is the area of the circle? ($\pi = \frac{22}{7}$)
Answer & explanation
Correct answer: option 1
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
