Answer:
500π in^3
Step-by-step explanation:
The radius is half the diameter, so the radius is 5 in. Since the height is four times that, the height is 20 in.
The equation for the volume of a cylinder is:
We can plug in the radius and height:
5n-10-n=14.8
6n-10=14.8
6n=24.8
24.8. divided by 6
n=4.something
Answer:
the numerical length of segment BD is = 19
Step-by-step explanation:
Given the information that point C is on the segment BD, and understanding that the total segment BD must equal the addition of the two parts on which it is divided by point C, we write the following equation:
BD = BC + CD
now we replace each of the above by their expression in x:
( 3 x + 4 ) = (2 x - 1 ) + (2 x)
and we solve for x in this equation:
3 x + 4 = 2 x + 2 x - 1
3 x +4 = 4 x - 1
4 + 1 = 4 x - 3 x
5 = x
Therefore, we can now obtain the length of segment BD:
BD = 3 x + 4 = 3 (5) + 4 = 15 + 4 = 19
There are two ways to solve this. One way is to use proportions:
380/10 = x/55
Cross multiply:
20900 = 10x
Divide:
x = 2090
Your answer is B
