Item 16 A sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. What is the difference of the vol
Zigmanuir [339]

Answer:

672\pi \text{ cm}^3.

Step-by-step explanation:

We have been given that a sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. We are asked to find the difference of the volumes of the spheres.      

We will use volume formula of sphere to solve our given problem.

\text{Volume of sphere}=\frac{4}{3}\pi r^3, where r is radius of sphere.

The difference of volumes would be volume of larger sphere minus volume of smaller sphere.

\text{Difference of volumes}=\frac{4}{3}\pi(\text{8 cm})^3-\frac{4}{3}\pi(\text{2 cm})^3

\text{Difference of volumes}=\frac{4}{3}\pi(512)\text{ cm}^3-\frac{4}{3}\pi(8)\text{ cm}^3

\text{Difference of volumes}=\frac{4}{3}\pi(512-8)\text{ cm}^3

\text{Difference of volumes}=4\pi(168)\text{ cm}^3

\text{Difference of volumes}=672\pi\text{ cm}^3

Therefore, the difference between volumes of the spheres is 672\pi \text{ cm}^3.

What is the difference between the height and the slant height of a pyramid?
monitta
The height is always measured perpendicular to the horizontal surface on which the pyramid rests, whereas the slant height is measured perpendicular to one edge of the base to the vertex, and, as we would say, appears to be slanted.

Studio fee:$8 per hour <br> Vase:$10
aleksandrvk [35]

Answer:

4.5 hours

Step-by-step explanation:

So, let's write a function p(x) which represents the total cost.

Let's let x represent the amount of hours.

The cost of a piece is a constant 10.

And there is a $8 fee per hour. In other words:

p(x)=8x+10

We spent a total of $46.

So, substitute in 46 for p(x) and solve for x:

46=8x+10

Subtract 10 from both sides:

36=8x

Divide both sides by 8:

x=36/8

Reduce:

x=4.5

So, we spent about 4.5 hours.

How to get 1/2x 2 1/2??
BabaBlast [244]

Answer:

1 1/4

Step-by-step explanation:

You are multiplying a fraction by a mixed number so you have to turn the mixed number into an improper fraction.

2 1/2 -- to do this you have to multiply the denominator by the whole number, then add the numerator.

2*2= 4   4+1=5

2 1/2 = 5/2

Then, you multiply normally

1/2 x 5/2 = 5/4

5/4= 1 1/4

So, you answer would be 1 1/4

Hope this helps!!
