V = 1/2 * (4/3) * 3.14 * r^3
V = 2/3 * 3.14 * r^3
V = 2.09 * r^3

Since the bowl is in the shape of a hemisphere, the radius of the bowl is half of its diameter. Let's say the diameter is 20 cm, then the radius would be 10 cm.

V = 2.09 * 10^3
V = 2.09 * 1000
V = 2,090 cm^3

Rounded to the nearest whole number, the volume of the bowl is 2,090 cm^3, which is closest to option N. 2,786 cm^3.
