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.

Jan 06, 2020 · Identify the radius of a circle. The radius is the length from the center of a circle to the edge of the circle. You can measure this in any direction and the radius will be the same. The radius is also one half of the diameter of a circle. This formula will calculate the volume of a sphere given its radius. How It Works. The volume of a sphere is given by the above formula where π is a constant approximately equal to 3.14159265 and r is the radius. This formula will calculate the volume of a sphere given its radius. How It Works. The volume of a sphere is given by the above formula where π is a constant approximately equal to 3.14159265 and r is the radius.

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.
