Question

from a circular sheet of radius 8 cm ,a circle of radius 4cm is removed find the area of remaining sheet​

Answer 1

Answer:

$\frac{96}{7}$ or 13.714

Step-by-step explanation:

area o f circle with 8cm radius = $\pi$$r^{2}$

=$\frac{22}{7}$x$8^{2}$

= 64

area of circle with radius 4cm = $\pi$$r^{2}$

=$\frac{22}{7}$x$4^{2}$

=$\frac{352}{7}$

remaining area = 64- $\frac{352}{7}$

= $\frac{448-352}{7}$

=$\frac{96}{7}$ or 13.714
