What is lateral area formula?
The lateral area of a figure is the area of the non-base faces only. (For a rectangular prism, any pair of opposite faces can be bases.) The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism. This is summarized by the formula: LA 5 hP.
How do you calculate volume and surface area?
Surface Area Formulas:
- Volume = (1/3)πr2h.
- Lateral Surface Area = πrs = πr√(r2 + h2)
- Base Surface Area = πr2
- Total Surface Area. = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
What is the volume of a solid cylinder in cm3?
The volume of a solid cylinder is 448π cm3 and height 7 cm. Find its lateral surface area and total surface area. Let the radius of the base and height of the cylinder be r cm and h cm respectively. Then, h =7 cm Was this answer helpful?
How do you find the height of a cylinder with radius?
1 Make sure the surface and radius are in the same units and radius in is radians. 2 Subtract 2πr² from the surface area. 3 Divide the result of step 1 by 2πr. 4 The result is the height of the cylinder.
How do you find the volume of a 10 inch cylinder?
For example, the height is 10 inches and the radius is 2 inches. First, we find the area by 3.14159 x 2 2 = 3.14159 x 4 = 12.574, then multiply that by 10 to get 125.74 cubic inches of volume. Using a higher level of precision for π results in more accurate results, e.g. our calculator computes the volume of this cylinder as 125.6637 cu in.
How do you find the size of a cardboard cylinder?
Enter the external radius of the cylinder. The standard is equal to approximately 5.5 cm. Determine the internal cylinder radius. It’s the internal radius of the cardboard part, around 2 cm. Find out what’s the height of the cylinder, for us it’s 9 cm.
