Do you mean volume or surface area?
volume = 4/3 x pi x r^3 (four divided by three, multiplied by pi, multiplied by radius cubed).
surface area = 4 x pi x r^2 (four multiplied by pi, multiplied by radius squared).

Why does the formula for the volume of a sphere work?
Because when working out volumes the answer is given in cubic units and the radius in the formula for finding the volume of a sphere is cubed: Volume of a sphere in cubic units = 4/3*pi*radius3
How do you find the radius of a sphere given the height?
The radius of a sphere is 1/2 of its height.
What are 5 formulas that use pi in geometry?
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
How do you find the diameter of a sphere with a given volume?
Make the radius the subject of the formula 4/3*pi* radius3 = volume and then double it to give the diameter.
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
What is the volume of a sphere of radius 7cm?
The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
Given a sphere with radius r the formula 4r2 gives?
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
The radius of a sphere is given by the formula r 0.7 5V 13 where V is its volume Find the radius of a spherical tankthat has a volume of 32 3 cubic meters?
What is the radius of a sphere is given by the formula r 0.7 5V 13 .that has a volume of 32 3 cubic meters where V is its volume. Find the radius of a spherical tank
How do you work out the volume of a sphere with a known diameter?
The volume inside a sphere (that is, the volume of the ball) is given by the formula:-Volume = 4/3πr3where 'r' is the radius of the sphere and 'π' is the constant piThe diameter of a sphere is two times its radius, thus a sphere 8 meters in diameter has a radius of 4 meters.
Why does the formula for the volume of a sphere work?
Because when working out volumes the answer is given in cubic units and the radius in the formula for finding the volume of a sphere is cubed: Volume of a sphere in cubic units = 4/3*pi*radius3
How do you find the radius of a sphere given the height?
The radius of a sphere is 1/2 of its height.
What are 5 formulas that use pi in geometry?
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
Formula of a radius when the area is given?
Since you said radius, I assume you mean Circle or Sphere. Circle: Area = Pi * radius^2 therefore, Radius = Square Root of (Area/Pi). Sphere: Area = 4/3 Pi * Radius^3 therefore, Radius = CubeRoot of (3/4 * Area/Pi)
Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
How many gallons are in 1 radius foot?
Given only one radius measure, the most likely shape is a sphere. A sphere with a 1 foot radius has a volume of 26.1 Imperial gallons (31.3 US gal). Given only one radius measure, the most likely shape is a sphere. A sphere with a 1 foot radius has a volume of 26.1 Imperial gallons (31.3 US gal).
