Why do you square the radius when finding the volume of a cylinder?
Because the volume of the cylinder is proportional to the cross sectional area of the cylinder. The cross sectional area is a circle and the area of a circle is pi*r2.
If a cylinder holds a volume of 100 cm and is 30 cm tall which is the area of the bottom cylinder?
I assume the volume is 100 cubic cm and NOT 100 cm. The volume of a cylinder is cross-sectional area * height 100 = cross sectional area * 30 so that the area of the bottom, or cross section, is 100/30 = 3.333... sq cm
What is cc volume of a cylinder 4.145 wide x 0.150 deep?
Volume of a cylinder = cross-sectional area times height
How do you find the volume of a cylinder when the diameter and height are given?
Divide volume by height will give you cross sectional area. The cross section of a cylinder is a circle. Area of a circle= π r2 divide your value of cross sectional area by π square root this value and multiply it by 2 that value is diameter.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
