The correct is one is; A cylinder is like a stack of circles. The volume of the cylinder would be the area of the circle multiplied by the height of the cylinder. The height of the cylinder represents how many circles are in the stack. Therefore, we get the formula πr²h, where πr² represents the area of the circle and h the height of the circle.
Answer:
n = 8
Step-by-step explanation:
2n - 5 = 11
2n = 11 + 5
2n = 16
n = 16/2
n = 8
Look at the picture.
The triangle ADC and the triangle CDB are similar.
Therefore corresponding sides are all in the same proportion:
Answer: 4√3
Answer:
The speed of sound is 
Step-by-step explanation:
Let
x-----> the speed of sound
we know that
so
solve for x
20n-n-11n =16
20n-12n=16
8n=16
n= 16/8
n=2
