Question

in the given figure ABC is diameter if a b is equal to 3 cm and ac is equal to 4 cm and angle A is equal to 90 degree find the area of shaded region​

Answer 1

area of triangle = 1/2 x b x h

=1/2 x 3 x 4

=6 cm2

to find bc,

bc2 = ab 2 + ac2

= 3 2 + 4 2

=9+16

= 25

= 5 cm

area of circle = pie r 2

= 22/7 x 25/4

multiply it

and

to find area of shaded region =area of circle- area of triangle

and

find area of shaded region.

Answer 2

Step-by-step explanation:

BC =√(4)² + (3)²

BC=√16+9

BC=√25

BC = 5cm

Radius =2.5cm

Area of circle = πr²

22/7 × (2.5)²

22/7 × 6.25

=19.625cm²

area of triangle = ½ ×base ×height

1/2×3×4

=6cm²

Area of shaded region =

area of circle area of triangle

19.625-6

=13.625cm²
