Question

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

Answer 1

here is your answer
height of cylinder = 4cm
we know volume of cylinder =
$\pi \: r {}^{2} \: h$
pi r^2h=196 pi
pi gets cancelled
r^2h=196
h=4
r^2=196/4=49
r= 7
curved surface area of cylinder = 2pi rh
2 ×22/7×4×7=176 cm^2
total surface area of cylinder = 2 pi r(r+h)
2*pi*r*(r+h)
484 cm^2

Answer 2

Lateral surface area of cylinder is 176& total surface area of cylinder is 484.
