Question

find the area of shaded region​

Answer 1

Answer:

HEY MATE

Step-by-step explanation:

$area \: of \: sector = \pi \: r^{2} \div 4$

$area \: of \: sector = 113.097$

but we can't find area of shaded region due to insufficient data....

give area of unshaded circle first...

Answer 2

Answer :

101.8

Explanation :

Given :

• Quadrant radius = 12

According to the question :

Area of Quadrant = $1 / 4\:πR^2$

= $1 / 4\:×\:22 / 7\:×\:12^2$

= 113.14

Finding Radius = 2πR = 12

= 2 × 22 / 7 × R = 12

= 44 / 7 × R = 12

= R = 12 × 7 / 44

= 21 / 11

= 1.90

Radius = 1.90

Area of circle :

= $πR^2$

= 22 / 7 × 1.90 × 1.90

= 11.34

To find :

Area of the shaded region :

Area of the quadrant - Area of the circle

=> 113.14 - 11.34

=> 101.8
