ok
number one is right prism
number two is volume
number 3 is (4/3) pi r^3
number four is side length

Can anyone please show the work on how to do this, with the answer because no one in my family knows.
And also.
1.A __ prism has lateral faces that are perpendicular to the two bases.
2.You can determine the __ of an irregular shaped object by measuring its displacement.
3.The volume V of a sphere of radius r is given by the formula V=
4.The __of a pyramid are the faces of the pyramid that are not the base.
Please help me :/
Hello darknightcatAssuming that the dimensions on the diagram are in cm, the solid is a hollow cylinder of length 7 cm and internal and external radii 4 cm and 8 cm, respectively. Its cross-sectional area is therefore:
and its volume is:
The density is the mass divided by the volume. So its density is:
The missing words are: 'lateral faces' or 'slant faces'4.The __of a pyramid are the faces of the pyramid that are not the base.
