Answer:
186.29 cm^2
Step-by-step explanation:
radius = 20/2= 10
area of circle = πr^2
= 22/7*10*10
= 2200/7 cm^2
area of trapezium= 1/2(12+20)*8
=1/2*32*8
=32*4
=128 cm^2
area of shaded region=2200/7 - 128
=1304/7
=186.29 cm^2
Find the area of the shaded region.
The diameter of the circle = cm
So, radius of the circle
= cm = cm
We know that:
So, area of the circle
= cm²
= cm²
= cm²
= cm²
We know that:
So, area of the trapezium
= cm²
= cm²
= cm²
= cm²
= cm²
Area of shaded region
= cm²
= cm²
= cm²
= cm²
The area of shaded region is cm².
