Answer:
Is it 2?
Step-by-step explanation:
The answer
1 /3 radius^2 x height 3
Pi/3 *r^2 x 9 3 = 3 pi ^2
r=1, volume = 3 pi
r=2, volume = 12 pi
r=3, volume = 27pi
Answer:
10%
Step-by-step explanation:
Given:
Total number of racers = 270
Number of racers completed the race = 243
Number of racers gave up = 20
Now,
The number of racers who did not complete the race
= Total number of racers - Number of racers completed the race
= 270 - 243
= 27
Therefore,
The percentage of racers who did not complete the race
=
=
= 10%
