Answer 2

Answer:

250.25

Step-by-step explanation:

QRS is a semicircle of radius RS as 7cm, area= pir^2 which is 77cm^2

PQ is a semi circle with diameter 7 so radius is 7/2 which means area is 77/4cm^2

radius of whole circle is 10.5cm

area is 346.5cm^2

area of shaded region+ 346.5-(77+77/4)

346.5-96.25

250.25

Hope it's clear. Sorry if i made any calculation errors:)
