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.
What is the surface area of a sphere with a radius of 7 units?
The surface area of a sphere is given by the formula A = 4 pi r2A = 4 (pi)(49)A = 196 piA = about 615.75 square units
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)
What is the answer for the hemisphere?
The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².
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
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
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?

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)
How much space will a 30Cm in a diameter metal ball occupy?
The volume of a sphere can be calculated using the formula V = (4/3)πr^3, where r is the radius of the sphere. Given that the diameter is 30 cm, the radius would be 15 cm. Plugging this into the formula, the volume of the sphere would be approximately 14,137.17 cubic centimeters.
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.
