Answer 3

ok, so the diameter is 5 inches, what is the radius?

(2 x radius = 1 x diameter)

Answer 4

the volume formula is

\[V = \frac{1}{3} \pi r^2h\]

so when you find the radius (r)

remember the height (h) = 3r

when you get both values, and you as asked to use pi = 3.14

the substitute the values into \[V = \frac{1}{3} \times 3.14 \times r^2 \times h\]

hope it helps
