Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = × 3.14 × 9.3³
= × 3.14 × 804.357
=
≈ 3367.6 cm³ ( to the nearest tenth )
The probability to choose letter n is 
. After drawing letter n there left 25 letters and the probability to choose the letter w is 
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is 
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is 
.
Using the product rule for probabilities, you can obtain that
