Q. A cone has a diameter of

10

units and a height of

21

units. Find its volume rounded to the nearest whole number.

Volume

Identify Formula and Values: Identify the formula for the volume of a cone and the given values. $\newline$ The formula for the volume of a cone is $V = (\frac{1}{3})\pi r^2 h$ , where $r$ is the radius and $h$ is the height. The given diameter is $10$ units, so the radius $r$ is half of the diameter, which is $5$ units. The height $h$ is given as $21$ units.
Substitute Values into Formula: Substitute the values into the formula. $\newline$ Using the radius of $5$ units and the height of $21$ units, the volume $V$ can be calculated as follows: $\newline$ $V = \frac{1}{3}\pi(5)^2(21)$
Calculate Volume: Calculate the volume. $\newline$ First, calculate the radius squared: $\newline$ $5^2 = 25$ $\newline$ Then, multiply by the height: $\newline$ $25 \times 21 = 525$ $\newline$ Now, multiply by $\pi$ (using $3.14$ as an approximation): $\newline$ $525 \times 3.14 = 1648.5$ $\newline$ Finally, divide by $3$ to get the volume: $\newline$ $1648.5 / 3 \approx 549.5$
Round to Nearest Whole Number: Round the volume to the nearest whole number. $\newline$ The volume of the cone is approximately $549.5$ cubic units. When rounded to the nearest whole number, the volume is $550$ cubic units.
