A cylindrical water tank has a volume of 16,880 dm³. find the radius of a water tank if its height is 42 dm.

V= r²h

16,800dm³=r²(42dm)

400 dm²= r²

20 dm= r

The edge of a cube is 32 cm. What is the volume of a cube?

V= s³

= (32 cm)³

V= 32,768 cm³

V= lwh

= (16 dm)(14 dm)(8 dm)

V = 1792 dm³

A rectangular pool measures 16 dm by 14 dm and 8 dm. What is the volume of water in the pool?

Rectangular prism

V= r³

=(3.14)(7 m)³

= (3.14)(343 m³)

V = 1,436.03 m³

Find the volume of a sphere whose diameter is 14 cm.

Created by Mr. S. Gier

V= ⅓r²h

128.22 cm³ =⅓(3.14)(3.5cm)²h

128.22 cm³ = ⅓(3.14)(12.25 cm²)h

128.22 cm³ = 12.82cm²h

10 cm = h

The volume of a cone is 128.22 cm³. Find the height of the cone if the diameter is 7 cm.

Created by Mr. S. Gier

V= ⅓s²h

4,608 m³= ⅓(12 m)²h

4,608 m³= ⅓(144 m²)h

4,608 m³=48 m²h

96 m = h

A base edge of a square pyramid is 12 m. What is the height of the pyramid if the volume is 4,608 m³?

Created by Mr. S. Gier

V= ⅓r²h

=⅓ (8 cm)²(25 m)

= ⅓(64 m²)(25 m)

V= 533.3321 m³

V= 1674.67 m³
