Question

solve this area of circle based question

Answer 1

area of ∆ABC=1/2×b×h

ar(ABC)=1/2×AB×AC

ar(ABC)=1/2×3×4

ar(ABC)=6cm^2

in ∆ABC By pytha thm

AB^2 +AC^2=BC^2

3^2+4^2=BC^2

9+16=BC^2

BC^2=25

BC=√25

BC=5cm

diameter of circle =5cm

radius of circle=5/2cm=2.5cm

area of circle=πr^2

area of circle= 3.14×2.5×2.5

area of circle=19.62cm^2(approximately)

area of shaded region=area of circle-ar(ABC)

area of shaded region=19.62-6

area of shaded region=13.62cm^2(approximately)

hope it will help you :)
