Answer 2

Correct!

Answer 3

\(V_{cylinder} = \pi r^2 h\)

\(V_{cylinder} = (3.14) (8)^2 (10)\)

\(V_{cylinder} = (3.14) (64) (10)\)

\(V_{cylinder} = 2009.6\)

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

\(V_{sphere} = \dfrac{4}{3} (3.14) (7)^3\)

\(V_{sphere} = \dfrac{4}{3} (3.14) (343)\)

\(V_{sphere} = 1436.02\)

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

\(V_{cone} = \dfrac{1}{3}(3.14)(10^2)(20)\)

\(V_{cone} = \dfrac{1}{3}(3.14)(100)(20)\)

\(V_{cone} = 2093.33\)

Answer 4

1436.03*
