The formula is: volume = 4/3 x pi x radius3. So, just replace the radius with 3, do the calculations, and you will obtain the volume (in cubic inches, in this case).
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
The formula for the surface area of a sphere is 4πr² and the formula for the volume is (4/3)πr³, where r is the radius of the sphere. Setting 4πr² equal to 588 and (4/3)πr³ equal to 1372, you can solve for the radius by equating the two expressions and taking the cube root of the result. Once you have the radius, you can calculate the surface area using the formula and divide it by the volume to find the ratio.
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 any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
SA = 4pi62
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
To calculate the surface area of a sphere use the formula - 4pr2 r being the radius of the sphere. and 'p' being pi 3.14...
V = ~113.097 cubic inches.
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
the formula for surface area of a sphere is 4pi(r squared) so do 4x3.14x144 equals 576 pieunits^2
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.
Based on what? If you know the radius, you can use the formula for a sphere - which is a good approximation in the case of Earth and Moon.
you measuresit by the radius
The water displacement of a sphere can be calculated using the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the sphere. The volume of water displaced by the sphere is equal to the volume of the sphere when it is submerged in water.
The formula for the surface area of a sphere is 4πr² and the formula for the volume is (4/3)πr³, where r is the radius of the sphere. Setting 4πr² equal to 588 and (4/3)πr³ equal to 1372, you can solve for the radius by equating the two expressions and taking the cube root of the result. Once you have the radius, you can calculate the surface area using the formula and divide it by the volume to find the ratio.
