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.
A(5) = 4 25
The formula for the volume of a sphere is: 4/3*pi*radius^3 measured in cubic units
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
C = 2(pi) r circumference of a sphere = 2*pi*radius or pi*diameter (Any circular circumference is the same for a perfect sphere.)
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
you measuresit by the radius
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
The formula for the volume of a sphere is based on the radius of the sphere. It is equal to 4/3 multiplied by pi, multiplied by the radius cubed.
diameter/2
Just insert the radius into the formula for the volume a sphere, and do the calculations. The formula is: V = (4/3) pi radius3
Volume=(4/3)π(radius of sphere)^3
volume = 4/3 pi * (cubed radius)
The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
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)
Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed
