If the perimeter of a circle is 88 cm, then what is the area of the circle? ($\pi = \frac{22}{7}$) |
616 m2 566 m2 886 m2 446 m2 |
616 m2 |
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 |
