Hi there! :)
Answer:
![\huge\boxed{V = 359.01 mm^(3) }](https://img.qammunity.org/2021/formulas/mathematics/high-school/rpf1hub727l6s4hemwf4kh6ikyi8tu352c.png)
Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
