Question

John buys big ice-cream cylindrical Jar and sells it for $1 each ice-cream cone.

Each cone has around 30 cubic cm of ice-cream in it.

  Jar has diagonal 20 cm. and its height is 3 times of width.

If he sells the whole jar, and He originally bought it for $7 does he make profit out of selling the jar?

Answer 1

John makes a profit. Volume of ice cream cylinder is pi, π (3.14) times radius (20cm/2) squared, time height (3 x 20cm) = 3.14 x 100 square cm x 60cm ≠18850 cubic cm. With 30 cubic cm per cone, a cylinder contains ice cream for about 628 cones, and sell for $628 dollars.
