A drum 40cm in diameter contains 88 liter of oil calculate the depth of the oil in the drum

Answer 1

d = diameter = 40 cm

A = Area of circle

V = Volume

h = depth

1 L = 1 dm³

1 dm = 10 cm

1 L = ( 10 cm )³

1 L = 1000 cm³

88 L = 88000 cm³

V = 88000 cm³

A = d² π / 4

V = A ∙ h

V = d² π / 4 ∙ h

88000 = 40² π / 4 ∙ h

88000 = 1600 π / 4 ∙ h

88000 = 400 π ∙ h

88000 / 400 π = h

220 / π = h

h = 220 / π

h = 70.02817496 cm

h ≈ 70 cm
