Question

A cone has a diameter of 18 units and a height of 8 units. What is its volume?

Answer 1

`\bold{answer \: \: : } \\ \rm{volume = (1)/(3) \pi{r} ^(2) t} \\ = (1)/(3) * 3.14 * {(18 / 2) }^(2) * 8 \\ = (1)/(3) * 3.14 * {9}^(2) * 8 \\ = (1)/(3 ) * {3.14} * 81 * 8 \\ = (1)/(3) * 254.34 * 8 \\ = (1)/(3) * 2034.72 \\ = (2034.72)/(3) \\ = \boxed{ \boldsymbol{678.24 }\: \: \rm{units}}`
