That's not too hard to show. But first, you have to be comfortable enough with
calculus that the idea of a triple integral doesn't scare you. We're pretty sure
that the question can't be answered without spending a few minutes working
with one of them.

What is the volume of a sphere with a surface area of 452.39cm2?
Surface area of sphere = 4r 4 xπ x r2 = 452.39 cm2 r2 = 452.39/(4) = 36.01831210191 cm2 r = sqrt(36.01831210191) = 6 cm(approximately) And volume is given by V = 4πr3 = 4 x π x 63/3 cm3 = 905.46912199289 cm3
What is 4r-48?
4r-48 = -44
How do you get -2 equals 4r plus s solving for s?
s = -2 -4r
How to solve 10 plus 4r 30?
If you mean: 10+4r = 30 then it works out that r = 5
What is -4r-9 plus r?
-13
Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
What is the volume of a sphere with a surface area of 452.39cm2?
Surface area of sphere = 4r 4 xπ x r2 = 452.39 cm2 r2 = 452.39/(4) = 36.01831210191 cm2 r = sqrt(36.01831210191) = 6 cm(approximately) And volume is given by V = 4πr3 = 4 x π x 63/3 cm3 = 905.46912199289 cm3
What is 4r r in simplest form?
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
What is the answer to -2 equals 4r plus s solving for s?
-2=4r+s s=-4r-2 or s=-(4r+2)
What is 4r-48?
4r-48 = -44
What is 4(2r plus 3s) - 4r?
It is 4r + 12s
What is the anwer for 36 4r?
If 36 = 4r, r = 9
How would you solve 4r plus 13 equals 57?
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
If a radius of a sphere increase by a factor of 4 what does the factor of the volume increase?
64The formula to find the volume of a sphere is4/3 * pi * r3where r is the radius of the sphere. So if the radius is increased by a factor of 4, then the formula becomes4/3 * pi * (4r)3 = 4/3 * pi * 64r3showing that the volume increases by a factor of 64.
Can you factor the polynomial 4r plus 8rs plus 28r?
4r + 8rs + 28r 4r is a factor of every every term so the expression can be written 4r(1 + 2s +7) NOTE : The original expression can be simplified to 8rs + 32r and thus the factored expression becomes 4r(2s + 8).
What is 4r plus r in simplest form?
It is in its simplest form: 4r+r = 5r
How do you get -2 equals 4r plus s solving for s?
s = -2 -4r
