Find the capacity in litres of a storage jar shaped as a frustum, with end radii 12 cm and 10 cm and a height of 15 cm. (Take \π = 22/7 , 1 litre = 1000 cm³.)

Question

Accepted Answer

5.72 litres. V = 1/3 × 22/7 × 15 × (144 + 100 + 120) = 22/7 × 5 × 364 = 5720 cm³ = 5.72 litres. 5720 litres leaves the answer in cm³; 0.572 divides by 10000 instead of 1000; 3.83 litres drops the Rr term (244 instead of 364).

Find the capacity in litres of a storage jar shaped as a frustum, with end radii 12 cm and 10 cm and a height of 15 cm. (Take $π = \frac{22}{7}$ , 1 litre = $1000 cm^{3} .$ )
