Volume of Cylinders Unit 3: Geometric Applications of Exponents
Cylinder A cylinder is a three-dimensional figure that has two congruent circular bases. Height Base
Volume of Cylinders V = Bh = (r2)h Area is measured in square units. Volume is measured in cubicunits.
Volume of Cylinders - To find the volume of a cylinder, multiply the area of the base by the height. • volume of a cylinder =
Volume of Cylinders V = r2h 1. Find the volume V of the cylinder to the nearest cubic unit.
Volume of Cylinders 2. Find the volume V of the cylinder to the nearest cubic unit.
Volume of Cylinders 3. Find the volume V of the cylinder to the nearest cubic unit. 8 cm V = Bh 15 cm
Volume of Cylinders A juice can has a radius of 2 in. and a height of 5 in. Explain whether tripling the height of the can would have the same effect on the volume as tripling the radius. By tripling the height, you would triple the volume. By tripling the radius, you would increase the volume to nine times the original.
