Question

10. A circle of radius 3 cm is cut out from a rectangular piece of paper of
dimensions 10 cm x 11 cm. Find the area of the left over paper. ​

Answer 1

Area of reactangle is l*b
10*11= 110
Area of circle is 22/7*3*3=28.28
So area of left space= 110-28.28=81.29

Answer 2

The area would be 81.71 sq. cm.

Step-by-step explanation:

Since we have given that

Dimensions of rectangular piece of paper = 10 cm x 11 cm

So, Area of rectangular piece of paper is given by

$Length\times breadth\\\\=10\times 11\\\\=110\ cm^2$

Area of circle with radius 3 cm is given by

$\pi r^2\\\\=\dfrac{22}{7}\times 3\times 3\\\\=28.29\ cm^2$

So, Area of the left over paper is given by

Area of rectangle - Area of circle

$110-28.29\\\\=81.71\ cm^2$

Hence, the area would be 81.71 sq. cm.
