How do you find the height of a circle with the volume?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . Simplify.
How do you find the volume of a circular base?
About This Article
- Measure the circular base to get the diameter.
- Divide the diameter by 2 to get the radius.
- Calculate the area with the formula: A = πr^2, where r is the radius.
- Measure the height of the cylinder.
- Multiply the area by the height to get the Volume.
How do you find the area of the base of a sphere?
The steps to calculate the surface area of a sphere is:
- Step 1: Know the radius of the sphere.
- Step 2: Take the square of the radius by multiplying it by itself.
- Step 3: Multiply r2 by 4.
- Step 4: Multiply the value of 4r2 by the approximate value of pi, that is, 3.14.
- Step 5: At last, add the units to the final answer.
How do you do area of a circle?
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
What is the formula to find the volume of a sphere?
Sphere Formulas in terms of radius r: Volume of a sphere: V = (4/3)πr3 Circumference of a sphere:
How do you find the surface area of a circular shape?
This shape has a circular base and straight, parallel sides. This means that in order to find its surface area or volume, you only need the radius (r) and height (h). However, you must also factor in that there is both a top and a bottom, which is why the radius must be multiplied by two for the surface area.
How to find the diameter of a circle using a calculator?
You can find diameter of a circle by multiplying the radius of a circle by two: Diameter = 2 * Radius Area of a circle radius. The radius of a circle calculator uses the following area of a circle formula:
What is the surface area of a sphere equal to?
Surface area of a sphere is equal to the areas of entire face surrounding it. Area of a Sphere- It is the amount of region covered by the surface of a sphere. Total Surface Area- It is the sum of total area of all the surfaces be it curved surface or flat surface.
