The formula for the volume of a cylinder is

We know the diameter, so we can easily find the radius. The diameter is twice as long as the radius, so we divide the diameter by 2 to find the radius. This is equal to 6/2 = 3. Now, we plug our numbers into the formula.

This could also be written:

Both 27 pi cubic meters and 84.82 cubic meters are correct answers, so choose whichever one you think your teacher would prefer.
Answer:
A
Step-by-step explanation:
You multiply it and since 32mm is half it would be 64
Answer:
x = 43.5 or x = 87/2
Step-by-step explanation:
(x - 3)2 = 81
2x - 6 = 81
2x = 87
x = 43.5
Number of students taking Spanish class this year in Brooke's school = 60
Percentage increase in the number of students
taking Spanish class from last year = 25%
Then
Number of students that are taking Spanish
class more than last year = 25/100 * 60
= 15
Then
The number of students that took Spanish class last year = 60 - 15
= 45 students
So the number of students that took Spanish class last year was 45. I hope the answer is clear to you and the procedure is also easy for you to understand.
