(a) Mary and Cynthia were building a cone-shaped sand castle. After some time, the diameter of

V125BC [204]

Answer:

$\displaystyle V\approx 769.7\text{ in}^3$

Step-by-step explanation:

We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.

The volume for a cone is given by:

$\displaystyle V=\frac{1}{3}\pi r^2h$

Where r is the radius and h is the height.

Since the diameter is 14, the radius is 7.

And we are given that the height is 15.

Therefore, the volume will be:

$\displaystyle V=\frac{1}{3}\pi (7)^2(15)$

Use a calculator:

$\displaystyle V\approx 769.7\text{ in}^3$

The volume of the cone is approximately 769.7 cubic inches.

professor190 [17]

Answer:

60 push-ups

Step-by-step explanation:

Set up a ratio to represent the problem:

Molly : Liza

10 : 15

40 : ?

How did we get from 10 to 40?

You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.

10 : 15

x4 x4

40 : 60

So, Liza does 60 push-ups while Molly does 40.
