Question

Find the area of shaded region​

Answer 1

Answer:

First mention ...is it right angled triangle or not

if it is....then

by Pythagoras theory

h²=b²+p²

so here you will get AB(radius of the semicircle)

then area of shaded region = area of semicircle - area of the triangle...

hope it helps..

Step-by-step explanation:

----------------------------------------------------------------------

ABC is a right angled triangle.

So in that Hypotenuse²=base²+adjacent².

AB²=BC²+AC²,

Substitute the values given:

AB²=4²+3²,

AB²=16+9,

AB²=25,

AB=√25,

AB=5.

As you know,Area of Right Angle Triangle = ½ (Base × Perpendicular or adjacent).

1/2×4×3,

2×3=6.

Now the given diagram looks like a semi-circle in which the diameter is AB=5,

So the radius will be D/2=5/2=2.5.,

So the area of a semi circle=πr²/2,

3.14×2.5×2.5/2,

9.81 is the area of the entire figure.

So the area of the shaded region= area of figure-area of triangle,

9.81-6,

3.81 is the area of the shaded region.
