The area of the base of a cylinder is 22(pi) square feet, and the height is 10 feet. What is the volume in cubic feet?
bas area x height = 22pi x 10 220pi sq ft
what about cubic feet?
The answer should be in cubic feet
oh sorry cubic feet
Area = 22 pi sqft x 10 ft = 220 pi cubic ft
what about the r in the formula for volume? (pi)r^2 * h
See the cylinder has a circular base and the area of a circle is (pi)r^2 General formula for volume is V = area of base x height So, in case of a cylinder it becomes (pi)r^2 x h In your question it already says that area of base (that is (pi)r^2) is 22 pi sqft So u r given the value of (pi)r^2 itself. So just multiply by height
oooh ok. makes sense. thanks harkirat =]
