Question

What is the approximate volume of a cone with a height of 6 mm and radius of 18 mm?

Use 3.14 to approximate pi, and express your final answer to the nearest tenth.

Answer 1

@Michele_Laino i got 2034.7 mm3 could u make sure im correct

Answer 2

you have to apply the same formula as before for previous exercise, namely:
\[\Large V = \frac{{\pi \times {R^2} \times H}}{3}\]
where R is the radius, and H is the height of the cone respectively

Answer 3

i did

Answer 4

so we get:
\[\Large V = \frac{{\pi \times {R^2} \times H}}{3} = \frac{{3.14 \times {{18}^2} \times 6}}{3} = ...?\]

Answer 5

I got:
V=2034.72 mm^3

Answer 6

So your answer is correct!
