Question

Which is the appropriate volume of an aspirin tablet that is almost as big as a one- centavo coin?

A. 30 m^3
B. 20 L
C. 200 cm^3
D. 200 mm^3

Answer 1

• Appropriate volume of an aspirin tablet which is almost as big as a one centavo coin is 200 mm³.
• We know that diameter of one centavo coin is 15 mm. So radius will be 7.5 mm.
• Thickness of one centavo coin is 1.54 mm.
• Coin is in the cylindrical shape, so volume of cylinder is-

V = πr²h where r is the radius of the coin and h is the thickness or height of the coin.

V = 3.14 × 7.5 × 7.5 × 1.54 mm³

V = 272 mm³

According to your options, option D ( 200 mm³) is the nearest one to the exact answer.
