Question

Answer this question​

Answer 1

at first find the area of whole figure then find the unshaded region

now area of the shaded region -the area of the shaded region =ur answer

I hope this will help you

Answer 2

Answer:

Step-by-step explanation:

CYLINDER

GIVEN:

Height of cylinder (h) = 14cm

Radius of cylinder (r) = 7/2

CSA of cylinder= 2πrh

= 2×22/7×7/2×14

=2×22×7

=308

Therefore, CSA of cylinder is 308sq.cm

HEMISPHERE

GIVEN:

Radius of hemisphere (r) = 7/2

CSA of hemisphere= 2πr²

=2×22/7×7/2

=2×11

=22

Therefore, CSA of one hemisphere is 22sq.cm

Adding CSA of cylinder and two hemisphere

308+2×22

=352sq cm

180° sector

Radius(r) = 7/2

area of 180°sector= 1/2πr²

=1/2×22/7×7/2×7/2

=1/2×11×7/2

=19.25

Therefore, area of 180°sector is 19.25sq.cm

Total area of shaded area = CSA of cylinder and hemispheres – area of 180°sector

=352–18.25

=332.75

Therefore area of shaded area is 332.75 sq cm

Hope it is right
