B. Substitute in for the radius and simplify to get 189 = (1/3) * 16 * 4^2 * h, which simplifies to 189 = (1/3) * 256 * h.
C. Use the reciprocal to get about h = 189 / ((1/3) * 256) = 189 / (256/3) = 189 * 3 /256 = 21/256 = 0.082.
D. Use the inverse operation of multiplication to get h by itself.
E. Height is approximately 0.8 ft.
A cone has a radius of 4 feet on its base. The approximate volume of the
cone is 189 ft^3. Determine the height of the cone to the nearest tenth of a
foot. Use 3.14 for π. (5 points)
