Total surface area = (pi*32) + (2*pi*3*6) = (2*pi*32) = 63*pi square cm The height of the cylinder has to be 6 cm because the radius of the hemisphere is 3 cm which is also its height.
32 METER
Volume = pi*42*32 = 512pi cubic cm.
The volume of a cylinder is pi*(radius)^2*height. We are not given the radius here, but we know the circumference. Circumference is 2*pi*radius. So radius is equal to the circumference/(2*pi). We can then substitute this into the equation for volume to get: V=pi*(circumference/(2*pi))^2*height=(circumference)^2/(4*pi)*height._________________________________________________________________For your problem we have circumference=84 inches and height=32 inches. So:(84 inches)^2/(4*pi)*32 inches=7056 square inches/(4*pi)*32 inches=1764 square inches/pi*32 inches=56448 cubic inches/pi=17967.9564553 cubic inches which is about 17968 cubic inches.
The answer will vary, depending on which of the two is the height, and which is the diameter of the base. To get the surface area, add up the two circles and the mantle, that is, use the formula: area = 2 x pi x radius2 + 2 x pi x radius x height, or the equivalent (2 x pi x radius)(radius + height).
Combined volume = (pi*32*6) + (2/3*pi*33) = 226.1946711 or about 226 cubic inches The height of the cylinder has to be 6 inches because the radius of the hemisphere is 3 inches which is also its height.
