A can holds 753.6 cubic centimeters of juice. The can has a diameter of 8 centimeters. What is the height of the can?
Tresset [83]

height = 15 cm

the volume (V) of a cylindrical can is

V = πr²h ( r is the radius and h the height )

here d = 8 cm ⇒ r = 4 cm

π × 4² × h = 753.6

16πh = 753.6 ( divide both sides by 16π )

h = 753.6 / 16π = 14.99 ≈ 15 cm
