# How do you find the volume of a circle formula

Depending on the particular body, there is a different formula and different required information you need to calculate its volume. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above. Jan 07, 2020 · The volume of a cylinder is given by the formula V = πr 2h, and π is about the equivalent of 22/7 or 3.14. As a general rule of thumb, volume is area of the base times the height of the object. However, this will not work for shapes without equal bases, like a cone. Make sure you have accurate measurements.

Use the following additional formulas along with the formulas above. Given the radius of a hemisphere calculate the volume, curved surface area, circumference and total surface area Given r find V, A, C, K use the formulas above; Given the volume of a hemisphere calculate the radius, curved surface area, circumference and total surface area Depending on the particular body, there is a different formula and different required information you need to calculate its volume. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above.

Multiply the diameter by pi to get the circle's circumference: 12 x 3.142 = approximately 37.7 inches. Find the square of the radius: 6 x 6 = 36 square inches. Multiply the answer determined in Step 3 by pi to get the circle's area: 36 x pi = 113 square inches. Multiply... Jul 02, 2012 · This middle school math video shows how to use a formula to calculate the volume of a sphere. This middle school math video shows how to use a formula to calculate the volume of a sphere. Volume of a Cube Volume of a Cylinder Volume of a Triangular Prism Volume of a Cone Volume of a sphere formula The volume of a sphere is 4/3 x π x (diameter / 2) 3 , where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius 3 . Jun 14, 2016 · A quadrant is a quarter of a circle. So to work out the area of a quadrant, first work out the area of the whole circle (use the formula A = π ×r²) and then divide the answer by 4. Alternatively, you could substitute the radius of the quadrant directly into the formula A = ¼ πr².

Volume of a Cube Volume of a Cylinder Volume of a Triangular Prism Volume of a Cone Volume of a sphere formula The volume of a sphere is 4/3 x π x (diameter / 2) 3 , where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius 3 . A circle does not have a volume. The volume of an object is the measurement of how much an object holds. It is a cubic measurement and does not apply to two-dimensional objects such as circles. The formula for determining volume varies with the shape of the object. A cylinder that has a circular base has volume because it is three dimensional. A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). The circumference of a circle is found using this formula: Learn how to use this formula to find the area of a circle when given the diameter.

Volume of a quarter cylinder is equal to one fourth (1 ⁄ 4) of a volume of a cylinder with circle of that same radius r at its base. radius, r: height, h: centimeter foot inch kilometer meter mile see more units A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). The circumference of a circle is found using this formula:

A circle does not have a volume. The volume of an object is the measurement of how much an object holds. It is a cubic measurement and does not apply to two-dimensional objects such as circles. The formula for determining volume varies with the shape of the object. A cylinder that has a circular base has volume because it is three dimensional.

The area of a circle is 'pi' multiplied by the square of the circle's radius. The volume of a circle is zero. As a circle has only two dimensions. The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.
