Question

2. Height of a cylinder and radius of the base is 8cm and 10.5 cm. Find the curved surface
area, total surface area and the volume of the cylinder.


​

Answer 1

Answer:

C.S.A=527.52cm²

TSA= 1219.89cm²

Volume=2769.48cm³

Answer 2

Answer:

height = 8cm , radius=10.5

Curved surface area of cylinder = 2πrh

= 2×22/7×10.5×8

=528.0

Total surface area of cylinder=2πr(r+h)

=2×22/7×10.5(10.5+8)

=2×22/7×10.5×18.5

=1221.00

volume of cylinder= πr square h

=22/7×(10.5)square ×8

= 22/7×10.5×10.5×8

=2772
