Volume: 4/3*pi*radius3 = 140 By making the radius the subject of the above gives it a value of 3.221166265 cm Surface area: 4*pi*3.2211662652 = 130.387557 square cm

The surface area of a sphere with a volume of 3500pi is: 2,391 square units.

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.

sphere surface area = 4 * pi * (radius2) and: sphere volume = 4/3 * pi * (radius3) ( pi = 3.141592654 approx)

A sphere can either have a surface area of 432 m2 but not a volume of 864 m3, or it can have a volume of 864 m3 but not a surface area of 432 m2.

A sphere with a surface area of 324pi cubic inches has a volume of: 3,054 cubic inches.

Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3

A sphere having a diameter of 9.5 feet has a surface area of 283.53 square feet and a volume of 448.92 cubic feet.

depends on the shape... if its a sphere or a prism or what. You'll get different answers because they have different surface area to volume ratios. Sphere will give you the biggest volume for a given surface area.

The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.

Well, first of all, that's no sphere.-- A sphere with surface area = 300 has volume = 488.6.-- A sphere needs surface area of 304.6 in order to have volume = 500.But this is just a ratio exercise, not a geometry problem, so we'll just use the numbersgiven in the question. It's just some sort of wacky humongous paramecium:Surface area = 300Volume = 500Ratio of (surface area)/(volume) = 300/500 = 0.6 .

Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r: The surface area of the sphere will be 4πr2 The volume of the sphere = 4/3(πr3) Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.

because the surface area is spread out over the volume of mass

-- The ratio of 588 to 1,372 is 0.4286 (rounded) -- A sphere with surface area of 588 has volume closer to 1,340.7 . (rounded)

Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3

Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed

A sphere is a shape where the distance from the center to the edge is the same in all directions. This distance is called the radius ( r ). The formula for determining surface volume is Surface area = 4_r2 Volume = 4/3_r3.

-- "864m square" is not a volume. "864m cubed" is a volume.-- A sphere can't have those measurements.If it's really a sphere with surface area of 432 m2, then its volume is 844.3 m3.If it's really a sphere with volume 864 m3, then its surface area is 438.7 m2.-- The answer to the question is: The ratio of 432 m2 to 864 m2 is 0.5 .-- If those are really an area and a volume, then the ratio of 432 m2 to 864 m3 is 0.5 per meter.

A globe is a sphere in which two mathematical formulae are used to calculate its surface area and its volume: Surface area of a sphere = 4*pi*radius2 in square units. Volume of a sphere = 4/3*pi*radius3 in cubic units.
