Answer:
The diameter of the circle is 20 cm.
So, The radius of the circle is 20/2 = 10cm.
Now, The area of the circle is
4πR^2
=4 × 22/7×(10)^2
=1257.14
≈ 1257 cm^2
Now, The area of the rectangle is 40 × 60 = 2400 cm^2.
Therefore the area of the shaded part is 2400 - 1257 = 1143 cm^2.
Answer:
1144 cm²
Step-by-step explanation:
area of rectangle=40*60=2400 cm²
dia of circle d=20
so r=10 cm
area of the circle=πr²
=3.14*10*10
=314 cm²
thus shaded are
=2400-314
=2086 cm²
