First we have to find the radius:
4*pi*radius2 = 64*pi
Divide both sides by 4*pi and then square root both sides to find the value of the radius:
radius = 4 cm
Volume of a sphere = 4/3*pi*radius3
Volume = 268.0825731 or 268 cm3 to the nearest cubic cm

How do you find what the ratio of surface area to volume for a sphere is?
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
Do solids that have the same volume have the same surface area?
Not necessarily. Having the same volume does not mean having the same surface area. As an example, if you were to take a sphere with volume 4/3*pi*r^3, and a suface area of 4*pi*r^2, and compare it to a cube with sides 4/3, pi, and 4^3, you would find that they had a different surface area, but the same volume. Let the radius of the sphere be 2, that is r = 2. In this case the surface are of the sphere is about 50, and the surface are of the cube is about 80. So a sphere and a cube, both with a volume of about 33.51 (4/3 * pi * 8), have different surface areas.
Surface area of sphere with volume 0.2 meters?
For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
How do you find a volume of a sphere with a radius of 2mm?
Volume of a sphere = 4/3*pi*radius3 Volume = 4/3*pi*23 = 33.51032164 or about 33.5 cubic mm
How do you calculate the surface-area-to-volume-ratio?
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
What can you use to find the sphere surface area?
Surface area of a sphere = 4*pi*radius squared
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
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.
How do you find a sphere surface area where the radius equals 26cm?
The surface area of every sphere is (4 pi) times (the radius squared).Knowing that, you can find the surface area of not only the one you'reasking about right now, but of every sphere that ever was, is, or will be !
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
Find the surface area of a sphere with the volume of 523.6m cubed?
SA = ~314.159 m2
How do you find mass of a sphere when only radius is given?
Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
How do you find the lateral area of a sphere?
there would be no" lateral" surface to a sphere because it is round , only with a cube ,pyramid or rectangular object would you have lateral surface,although it is still possible to determine the surface area and volume of a sphere, the formula to calculate the area of a sphere is 4x pie x radius squared, to calculate the volume the formula is 4x pie x radius cubed divided by 3, to calculate a hemisphere you would divide the answer in half.
What is the volume of a sphere with a surface area of 78.5 yards squared?
First we have to find the radius: 4*pi*radius2 = 78.5 square yards Divide both sides by 4*pi: radius2 = 6.246831516 Square root both sides: radius = 2.499366223 yards Volume of a sphere = 4/3*pi*radius3 Volume = 65.40008284 cubic yards
How do you find what the ratio of surface area to volume for a sphere is?
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
To find a sphere's volume you could use V equals 4πr2?
No, because the volume of a sphere = 4/3*pi*radius3 in cubic units But the surface area of a sphere = 4*pi*radius2 in square units
What the ratio of surface area to volume for a sphere is?
first you must find the equations for the surface area and for the volume of a sphere. I believe the volume is 4/3 *pi *r^3, making the surface area 4*pi*r^2 the ratio is the one number over the other so: (4*pi*r^2)/(4/3*pi*r^3) = 3/r
What is the ratio of surface area to volume for a sphere with the following measurements surface area equals 588 M squared volume equals 1372 m to the Third?
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.
