The difference between the volume of cone and the volume of a cylinder?

Sergeu [11.5K]

Solution:

we have been asked to find

The difference between the volume of cone and the volume of a cylinder?

As we know that the volume of the cone is given by the formula

$V=\frac{1}{3} \pi r^2h\\ \\ \text{where h= height of cone, r=radius } \\$

And the volume of the Cylinder is given by the formula

$V= \pi r^2h\\ \\ \text{where h=Height, r=radius}\\$

The difference between the volume of cone and the volume of a cylinder can be calculated as below

$Difference=\frac{1}{3} \pi r^2h-\pi r^2h=-\frac{2}{3}\pi r^2h$

you buy a container of cat litter for $12.25 and a bag of cat food for xx dollars. the total purchase is $19.08, which includes

Tpy6a [65]

1.06(12.25 + x) = 19.08
12.25 + x = 19.08/1.06 = 18
x = 18 - 12.25 = 5.75

Therefore, the cost of the cat food is $5.75
