Answer:
plzz post the pic of circle
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:)
