A milkman sells 180 litres of milk in a day. If the angle representing home delivery in the pie chart is 80°, how many litres of milk does he supply to homes?

Answer: 40 liters
Explanation

Given:

Total milk sold = 180 liters

Angle for home delivery = 80°

Total angle in a pie chart = 360°

Fraction for home delivery = 80° / 360°

= 2/9

Milk supplied to homes = 2/9 × 180

= 40 liters
