Question

Suppose the diameter of the hemisphere is 24cm and total height of the

trophy is 28cm.

a) Find the curve surface area of cylinder.​

Answer 1

Answer:

2112cm²

Step-by-step explanation:

Given,

Diameter of the cylinder(2r) = 24cm

Therefore, radius(r) = 24/2 = 12cm

Height of the cylinder(h) = 28cm

Now,Curved Surface Area of the cylinder:-

2πrh = 2×(22/7)×12×28

= (2×22×12×28)/7

= 2×22×12×4

= 44×12×4

= 528×4

= 2112cm²
