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
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.
How are the formulas for the area of a circle and the volume of a cylinder related?
The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.
What is the cross sectional area of cylinder?
It is the same as that of an area of a circle which is: pi times radius squared.
What is the volume a cylinder of area is 7cm and diamiter is 20cm?
The [cross sectional] area is not consistent with the diameter.
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
How do you calculate the volume of a vertical cylinder tank?
Volume = Cross sectional Area x Height.
Cross sectional area of a cylinder?
= area of a circle = pi*r^2 or length x width if the cross section is longitudinal (since the area will be rectangular)
What formula you can use to find the volume of a cylinder?
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
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 do a cross sectional area of a rectangle?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
How do you calculate cross sectional area?
To calculate Cross Sectional Area: Width x Depth
How does cross sectional area affect resistance?
the larger the cross sectional area, the smaller the resistance
