Question

A 3cm×10cm rectangle sits inside a circle with radius of 12 cm

Answer 1

Answer:

422.39$cm^{2}$

Step-by-step explanation:

The shaded area is the area of circle minus the area of the rectangle.

So, area of circle is $\pi$$r^{2}$ = $\pi$$12^{2}$ = 144$\pi$ = 452.3893$cm^{2}$

area of rectangle is L x W = 10 x 3 = 30$cm^{2}$

So, the shaded area is 452.3893 - 30 = 422.3893$cm^{2}$
