Question

find the area of the shaded region if PQ =24cm , o is the center of the circle​

Answer 1

Answer:

the area of the shaded region = 161.54 cm²

Step-by-step explanation:

PQ=24cm ,PR =7 cm

We know that any angle made by the diameter QR in the semicircle is 90°.

∴∠RPQ=90°

In right angled ∆RPQ

RQ

2

=PQ

2

+PR

2

[By pythagoras theorem]

RQ²=24²+7²

RQ²=576+49

RQ²=625

RQ=√625cm

RQ=25cm

now find radius and area of triangle by using formula.
