Explanation:

Step1: Find cone radius

The diameter is 2 ft, so radius $r = \frac{2}{2} = 1$ ft.

Step2: Recall cone volume formula

Volume $V = \frac{1}{3}\pi r^2 h$

Step3: Substitute values ($\pi=3.14$, $r=1$, $h=\frac{3}{4}$)

$V = \frac{1}{3} \times 3.14 \times 1^2 \times \frac{3}{4}$

Step4: Simplify the expression

First, $\frac{1}{3} \times \frac{3}{4} = \frac{1}{4}$, so $V = 3.14 \times \frac{1}{4} = 0.785$

Answer:

0.785 cubic feet
