Answer— 2
Explanation- simple math
Answer:
2827.4
Step-by-step explanation:
V = πr2h this is the equation that can be used for these problems.
V= π(10)2(9)
the radius is 10 because the diameter is 20. Divide the given diameter by 2 to find the radius.
Answer:
The height is 15.992 in
Step-by-step explanation:
1. The equation for a cylinder is 
. In this case, the equation looks like 
2. Isolate h by dividing both sides of the equation by 
3. This leaves us with 
4. Solve for the left side, which leaves us with h = 15.992 (rounded to the nearest thousandth)
Answer:
Step-by-step explanation:
Given that,
...(1)
We need to find the value of 
.
Put n = 1 to find the first term.
Put n = 2 to find the second term.
Put n = 3 to find the third term.
Put n = 10 to find the tenth term.
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
We have, n = 10, a = 5 and 
So,
So, the value of is equal to 280.
Answer:
c = 22.8 miles/hr
Step-by-step explanation:
The ship A sails north at the rate of 14 mile per hour , it represent the opposite side of a triangle. Ship B start at the same point and move east at the rate of 18 miles per hour, it represent the adjacent side.
The other rate telling you how fast the distance between them are changing can be computed using the Pythagorean theorem, since the change in time is 1 hour. From 12 noon to 1 pm.
c = ?
a = 14
b = 18
c² = a² + b²
c² = 14² + 18²
c² = 196 + 324
c² = 520
c = √520
c = 22.803508502
c = 22.8 miles/hr
