Question

From a circular card sheet of radius 14cm , two circles of radius 3.5cm and a rectangle of length

3cm and breadth 1cm are removed find the area of the remaining sheet.​

Answer 1

Answer:

• Radius of the circular sheet = 14cm

Area =

$\pi{}^{2} = 22 \div 7 \times 14 \times 14cm {}^{2}$

$= 616cm {}^{2}$

• Area of 2 small circles = 2πr^2

$= 2 \times 22 \div 7 \times 3.5 \times 3.5cm {}^{2}$

$= 77.0cm {}^{2}$

• Area of the rectangle = l × b

$= 3 \times 1cm {}^{2} = 3cm {}^{2}$

• Area of the remaining sheet after removing the 2 circles and 1 rectangle.

$= 616cm {}^{2} - (77 + 3)cm {}^{2}$

$= 616cm {}^{2} - 80cm {}^{2} = 536cm {}^{2}$
