the diameter of a cone-shaped container is 4 inches, and its height is 6 inches .How much grater is the volume of a cylinder-sha
sveticcg [70]
The radius r used in below equations would equal 2in because it is half the given diameter of 4in.
The volume of the cone would be 
V = \frac{1}{3}  \pi r^2h \\ \\ V = \frac{1}{3} \pi (2in)^2(6in) = 8 \pi\ in^3

The volume of a cylinder with the same dimensions would be
V =  \pi r^2h \\ &#10;V =  \pi (2in)^2(6in) =  24 \pi in^3

The cylinder is 24 - 8 = 16 cubic inches greater.

You are riding the swings at a fair. What are the coordinates of your location after a rotation of 180°?
nekit [7.7K]

Answer:

(6, -3)

Step-by-step explanation:

The actual coordinates are x = -6 and y = 3

If we rotate 180 degrees and the center of rotation is at (0,0), all we need to do is invert the signal of each axis, that is, we invert the sign of the original x-coordinate and invert the signal of the original y-coordinate.

So the final x-coordinate is - (-6) = 6

And the final y-coordinate is - (3) = -3

So the coordinates will be (6, -3).

Ronny is selling coffee mugs for $3.50. So far, he has earned $301.00. Ronny needs to earn more than $371.00 in order to meet hi
mestny [16]
The easiest way to solve for this is to first find out how many he has sold right now. The way to find it is to divide the total amount of money (301) by the amount of each cup. (301/3.50) That should be equal to 86 cups. Now, you want to find the rest he needs to sell. The easiest way is to divide the number you want (371) by the number of each cup (371/3.50) That should be equal to 106. Since you want to know how many more he needs to sell you now need to subtract them. (106-86) That is equal to your answer, 20.
