Hello there, and thank you for asking your question here on

Short A. 1272 cm³

Why?

When finding the volume of a cone, you use the formula V = πr²h/3. R = 9, H = 15. V = π9²15/3 9² = 81 | 15 / 3 = 5 | 3.14 * 81 = 254.34 | 254.34 * 5 = 1271.2 1272 rounded.

Hope this helped you! ♥

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
