Question

How many cylindrical can of bottles 12 cm high and with 6 cm diameter could be filled from a tank containing 125 liters of detergent?

Answer 1

368 cans

Explanation:

Radius = 6/2 = 3cm

Capacity of each can

3.14 × 3² × 12

339.12 cm³

125 litres = 125000 cm²

No. of cans:

125000/339.12

368.6010852

Answer 2

368 cans.

Explanation:

Volume of 1 can = π r^2 h.

Here h (height) = 12 and r (radius) = 1/2 * 6 = 3 cm.

So V = π * 3^2 * 12

= 108π cm^3.

The tank hold 125 liters

= 125,000 cm^3, so:

Number of cans that could be filled = 125000/ 108 π

= 368.4.
