If a sphere has a volume of 36 pie units cubed if the radius is increased by a factor of what is the new volume of the sphere?
This exercise could have been a piece o' cake, and fun in its own right,if you had just told us what the "factor of ..." number is.By whatever factor the radius increases, the volume increases by the cubeof that number.
Surface-area-to-volume ratio in nanoparticles?
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.
What is the volume in gallons if the height of the cylinder 4 feet and radius is 1 foot?
The volume is 94 US gallons.
What is the volume of a sphere with 6 inch radius and 17 inch height?
A sphere cannot have a 17 inch height, if it has a 6 inch radius. If it has a 6 inch radius, the height (diameter, in this case), would be 2 times the radius, which is 12. If it was a sphere with 6 inch radius (and not using height), then you use the formula, 4/3(pi)r^3. = 4/3 * pi * 6^3 = 288 pi ≈ 904.779 inches cubed. Dingbot is: 1. over-sensitive to long answers, 2. correct to ping over-exact answers pasted from [Windows] Calculator. Folks, 4 to 6 significant figures are enough for us engineers and mechanics - any more is just bragging.
What is the volume of a cylinder in gallons with a radius of 21 inches and a length of 98 inches?
A cylinder with a radius of 21 inches and a height of 98 inches has a volume of 135,773.35 cubic inches. This cylinder would have a volume of 587.763 US gallons.
