D. 94 cubic feet

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have r = 3 ft and H = 10 ft. Substitute:

$V=\dfrac{1}{3}\pi(3^2)(10)=\dfrac{1}{3}\pi(9)(10)=\pi(3)(1)=30\pi\ ft^3$

$\pi\approx3.14$

Therefore

$V\approx30\cdot3.14=94.2\ ft^3\approx94\ ft^3$
