Question

5. From a circular sheet of radius 4 cm, a circle of radius 3 cm is removed. Find the area of the remaining sheet. (Take π = 3.14)

Answer 1

Answer:

22 $cm^{2}$

Step-by-step explanation:

Given circular sheet has the radius of 4 cm

Area of the circular sheet = π$4^{2}$ $cm^{2}$

Area of the circle removed = π$3^{2}$ $cm^{2}$

∴ Area of the remaining sheet = π$(4^{2} - 3^2)$ $cm^{2}$ = $\frac{22}{7}$x(16 - 9) $cm^{2}$ = 22 $cm^{2}$
