Directions: Find the missing dimension. Use a = 3.14. Write your
answers on a sheet of paper.
h

1. Volume of a Cone
r = 3 cm
h= 6cm
V= 56.52 cm3

Solution:
56.52cm3 = 3.14 (3cm x 3cm) h /3
56.52 cm3 = 28.26cm2 / 3 (h)
56.52 cm3 = 9.42 cm2 (h)
56.52 cm3 / 9.42 cm2 = h
6cm = h

2. Volume of a Sphere
r = 30m
V= 113, 040 cm3

Solution
V = 4/3 (3.14) (30m x 30m x 30m)
V = 4/3 (84,780 m3)
V = 339, 120 m3 / 3
V = 113, 040 m3

3. Volume of a Cylinder
r = 2.5m
h=6m
V= 117.75 m3

Solution:
117.75 m3 = 3.14 (r2) 6m
117.75 m3 = 18.84 m (r2)
117.75 m3 / 18.84 m = r2
6.25 m2 = r2
2.5 m = r

4. Volume of Pyramid
L = 16 cm
W = 3cm
H = 8 cm
V= 384 cm3

Solution
384 cm3 = 16cm x W x 8cm
384 cm3 = 128 cm2 (W)
384 cm3 / 128 cm2 = W
3cm = W

5. Volume of a Cylinder
r = 3 cm
h=10.5cm
V= 296.73 cm3

Solution
V = 3.14 (3cm x 3cm) (10.5cm)
V = 296.73 cm3
