a manufacturer of cat toys produces three different toys filled with catnip the toys are the shape of a cone cylinder sphere each with radius 3 inches the cone and the cylinder each have a height of 2 inches which statement about the toys are true choose all that apply help ?

Answers

Statements A, B, and C are true.

Step-by-step explanation:

Step 1:

A cone, a cylinder and a sphere all have radii of 3 inches. The cone and cylinder have heights of 2 inches.

The volume of the cone, V=\pi r^(2) (h)/(3). Here r = 3 inches and h = 2 inches.

So the volume of the cone  =\pi r^(2) (h)/(3) = \pi (3^(2)) (2)/(3) = 18.85 cubic inches.

The volume of the cylinder, V=\pi r^(2) h. Here r = 3 inches and h = 2 inches.

So the volume of the cylinder = =\pi r^(2) h= \pi (3^(2)) (2) = 56.55cubic inches.

The volume of the sphere, V=(4)/(3) \pi r^(3). Here r = 3 inches.

So the volume of the sphere=(4)/(3) \pi (3^(3))= 113.1 cubic inches.

Step 2:

Now we check to see which statements are true.

A. About 113 cubic inches of catnip will fit inside a sphere-shaped toy so it is true.

B. About 18.8 cubic inches of catnip will fit inside a cone-shaped toy so it true.

C. The sphere-shaped toy holds the most of the three so it is true.

D. No shape holds 169.6 cubic inches, so D is false.

E. The toys shaped like a cone and a cylinder do not hold the same amount of catnip in them. So it is false.

P.S. I couldn't see the options B, D, and E completely.

Answer:

y=1/2x.

Step-by-step explanation:

First, you would like to distrubte the fraction to make it become: 1/2x+1 on the right side. Second you would like to put it in y=mx+b form. Isolate y to y=1/2x. Then, you can start on (0,0), the orgin and they go up 1 and over 2 right.

How is the area of a sail related to the weight of the pilot on a hang glider?

Answers

The correct answer is:

The larger the surface area of the sail, the heavier the pilot can be and safely use the glider.

Explanation:

A hang glider must be able to support the weight of the pilot.  The air pushing up under the sail (wing) of the glider helps support the weight.  The more sail (wing) that you have, the more air pushing up, and the more weight it can hold.
The area of the sail is correlated to the weight of the pilot on the hang glider because the surface area of the sail needs to be able to lift ≤ (greater than or equal to) weight of the pilot.
