Answer:
Vol_prism = 48 (all answers should have the units cm^3)
Vol_pyramid = 25
Vol_cyl = 37.68
Vol_cone = 12.56
Vol_sphere = 113.04
Explanation:
This was a very compact problem (5 problems!) You read the chart top to bottom and each column is a different problem.
Vol of a prism:
V = l×w×h = 4×4×3
= 48 cm^3
Vol of a pyramid:
V = 1/3Base•h
= 1/3 (5×5)•3
= 25 cm^3
Vol of a cylinder:
V = pi•r^2•h
= pi•2^2•3
= pi•4•3
= 12pi = 12(3.14)
= 37.68 cm^3
Vol of cone:
= 1/3pi•r^2•h
= 1/3pi•2^2•3
= 4pi = 4(3.14)
= 12.56 cm^3
Vol of a sphere:
V = 4/3pi•r^3
= 4/3 pi•3^3
= 4/3 pi•27
= 36pi = 36(3.14)
= 113.04 cm^3
Pheewwwww! That was a lot! Hopefully you are just reviewing all your volume formulas. Hope this helps!
