Question

The volume of a cylinder of height 4cm is 196pie cm cube.find its lateral surface area and its total surface area.

Answer 1

Answer:

Step-by-step explanation:

v=196πcm³

h=4cm

we know that,

v=πr²h

196π=πr²*4

196=4r²

r²=49

r=7

LSA=2πrh

      =2*22/7*7*4

      =176cm²

TSA=2πr(r+h)

      =2*22/7*7(7+4)

      =44*11

      =484cm²
