Full solution

Q. What is the volume of this cylinder? Use

\pi \approx 3.14

and round your answer to the nearest hundredth.

10\,\text{m}

7\,\text{m}

cubic meters

Write formula for volume: The formula for the volume of a cylinder is $V = \pi r^2 h$ . We have $r = 7\, \text{m}$ and $h = 10\, \text{m}$ .
Substitute values into formula: Plug the values into the formula: $V = 3.14 \times 7^2 \times 10$ .
Calculate radius squared: Calculate the radius squared: $7^2 = 49$ .
Multiply values: Now multiply $\pi$ , the radius squared, and the height: $V = 3.14 \times 49 \times 10$ .
Perform final calculation: Do the multiplication: $V = 3.14 \times 490$ .
Perform final calculation: Do the multiplication: $V = 3.14 \times 490$ .Finish the calculation: $V = 1538.6$ cubic meters.
