Answer: 718 in^2.
Step-by-step explanation: To find the volume of a cone, you use the following equation:
V = π x r^2 x h x 1/3, where π is approximately 3.14, r^2 is the radius of the cone squared, h is the cone's height, and V is the volume of the cone. Since a cone's volume is one-third of a cylinder's, that's why we multiply by 1/3, in case you're confused about where the 1/3 comes from.
Now, we substitute the following so we can solve this problem:
V ≈ 3.14 x 7^2 x 14 x 1/3.
Now that we've filled in the following, we can solve it:
- 3.14 x 7^2 ≈ 153.86.
- 153.86 x 14 ≈ 2154.04.
- 2154.04 x 1/3 ≈ 718.01333333.
Therefore your answer is 718.01333333 in^2 or rounded to the nearest whole number is 718 in^2.
Let me know if this is right! :)
