A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 1/3x. Find the height of the cone in terms of y.

Answers

Great question! I had this question in Geometry on Edmentum.

Answer: Height of cone = 3y

Step-by-step explanation:

We know that the cylinder and the cone have the same volume. The cylinder has radius x and height y. We will make use of the formulas:

Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

Since the cone has radius 1/3x, we will have to make its height 3 times of y (the height of the cylinder) to make both the cylinder and the cone have the same volume.

So, the height of the cone is equal to 3y.

Hope this helps, and have a wonderful day! :D

1. V=1wh/3

4 x 3 x 9 = 108

108/3 = 36

2. V=lwh/3

22 x 21 x 35 = 16170

16170/3 = 5390

1. Answer:

16,170

Step-by-step explanation:

Length times width times height

L = 21 m

W = 22 m

H = 35 m

32 m times 22 m times 21 m = 16,170

Daniel and Edwin went to lunch. Daniel’s meal cost $20 and Edwin’s meal cost $18.50. They each left an 18% tip on the price of their own meal. How much did Daniel and Edwin pay in total?

Answers

Answer:

$45.43

Step-by-step explanation:

20 × 0.18 = 3.60

18.50 × 0.18 = 3.33

3.60 + 3.33 = 6.93

The total in tips is 6.93

20 + 18.50 = 38.50

The total meal cost is 38.50

38.50 + 6.93 = 45.43

The total of everything is 45.43

Store A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.

The domain of c(n) = 2.5n is all the real numbers.

For each store, drag the restriction needed on values of n for c(n) to model each situation.

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

We already did that, and the GCF of 112 and 7 is 7.

We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.

112/7 = 16
