Volume of this cone

ArbitrLikvidat [17]

Answer:

669.9 ft³

Step-by-step explanation:

The formula for volume of a cone:

$v=\pi r^2*\frac{h}{3} (3.14*radius*radius*\frac{height}{3} )$

$r = radius,\pi =pi,h=height.$

The radius is 8; the height is 10.

From here, we can just plug the numbers into the formula.

$\pi 8^2*\frac{10}{3} (3.14*8*8*\frac{10}{3} ) = 669.866666667.$

$669.866666667$ ≈ $669.9.$
