A. V = (1/3)πr^2h
B. 189 = (1/3)(3.14)(4^2)h
189 = (4.1867)h
189/4.1867 = h
45.14 = h
C. h ≈ 45.1 feet
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)
A. Use this formula:
B. Substitute in for the radius and simplify to get
C. Use the reciprocal to get about
D. Use the inverse operation of
to get h by itself.
D. Height is approximately
