Could a tutor please check my work?
question:
What is the surface area and volume of a pressure vessel in the form of a cylinder with each end in the form of a hemisphere, if the overall length is 12 meters and the diameter is 3 meters.
solution:
given:
radius = 1.5m
diameter = 3m
height or length = 12m
pi=3.14

Total surface area of a cylinder = 2*pi*r*h + 2*pi*r^2
TSA = 2*3.14*1.5*12 + 2*3.14*1.5^2
= 113.04 m^2 + 14.13 m^2
= 127.17 m^2
Volume of a cylinder = pi* r^2*h
V= 3.14*1.5^2*12
= 84.8 m^3
Is this correct?
