Name the solid with the description as a figure that has one base that is a rectangle and four lateral surfaces that are triangles. (1 point)

triangular pyramid
cone
rectangular prism
rectangular pyramid

2.
A solid with two parallel and congruent bases cannot be which of the following? (1 point)

cone
prism
cylinder
cube

17.
A cone has a radius of 15 cm and a volume of 540 cm3. Find the volume of a similar cone with a radius of 10 cm. (1 point)

54 cm3
240 cm3
160 cm3
360 cm3

18.
Find the surface area of a sphere with a radius of 5 meters. (1 point)

19.
Find the volume of a sphere with a radius of 5 meters. (1 point)

1. rectangular pyramid
2. cone
17. 240 cm

1. I don't know about 17, but the others are right.

2. I am not sure about 17 either. Do you know how to solve it?

3. I'm not sure. Please post 17 as a separate question, without my name.

4. I think 17 is correct.

If I remember the formula correctly it is
V = 1/3 times r^2 times h

What is given allows us to find h.
Then you can use 10 cm and the h to find the new volume.

5. 17. A "similar" cone would have the height and radius reduced by the same fraction (2/3 in this case). The volume would be reduced by a factor (2/3)^3 = 8/27. Multiply that by 540 and you get 160 cm^3.

6. I am confused! Is 17 240 or 160??

posted by Delilah
7. It's as drwls said -- 160 cm^3
