A.


B.


C.


D.

Answer 1

a: V=1/3*3.14*R2H

Answer 2

B:V=*3.14*R2H

Answer 3

C:V=LWH

Answer 4

D:V=4/3*3.14*R3

Answer 5

i think its a

Answer 6

Take look at this and let me know if it helps :) http://openstudy.com/study#/updates/54f20c99e4b09f47f4e3cad9 and no, it's not a

Answer 7

You need the formulas for the volume of a sphere and volume of a cone.

Answer 8

oh so is it d?

Answer 9

\(V_{cone} = \dfrac{1}{3} \pi r^2 h\)

\(V_{sphere} = \dfrac{4}{3} \pi r^3\)

Answer 10

a. is the volume of a cone
b. is the volume of a cylinder
c. is the volume of a rectangular prism
d. is the volume of a sphere
You need both the cone and the sphere.

Answer 11
