Question

A cylindrical water tank has a hemispherical bottom. Find its total surface area and its volume if the dimensions are

r=1.5 m
h=3 m

Please help me!

Answer 1

\[\huge SA = 2\pi r^2 + 2\pi r h\]
\[\huge V = \pi r^2 h\]
does that help?

Answer 2

where:
SA = surface area
r = radius
h = height
V = volume
