What is the capacity of the coffee mug, rounded to the
nearest mL?
The shape of the mug is cylindrical. Use the formula to
find the volume of the cylinder:

V = 3.14 (4 × 4)9
V = 3.14 × 16 × 9

V = 452.16 cm
The capacity of the coffee mug, to the nearest mL, is 452 mL.
Write which measure is more reasonable.
1. A soup ladle holds 150 L or 150 mL.
2. A garbage can holds 25 L or 25 kL.
