Answer:
Altitude of cylinder = 10 cm
Step-by-step explanation:
Given:
lateral surface area of cylinder = 90 cm²
Circumference of base = 9 cm
Find:
Altitude of cylinder
Computation:
Circumference of base = Circumference of cylinder
So,
2πr = 9
lateral surface area of cylinder = 2πrh
2πrh = 90
We know that; 2πr = 9
So,
9(h) = 90
h = 90 / 9
Altitude of cylinder = 10 cm
3/3 or 3 over 3
usually its like 3
_
3
but it can go anyway
Answer:
Step-by-step explanation:
The figure is a parallelogram. That means the y value of g is the same as the y value of H
G( ? , b)
The x value of G is a little harder. You have to be careful what you do to c.
A is at - c which means you need to add c to get to (0,0)
In addition, you go out d units to get to F. So the x value of G = c + d
the complete answer is G(c + d,b)
Answer:
The value of 
is 
.
Step-by-step explanation:
We know that the position function is given by
Velocity is defined as the rate of change of position. Therefore,
So, the velocity function is
When a body reaches a vertical velocity of zero, this is the maximum height of the body and then gravity will take over and accelerate the object downward. Thus,
We know that the ball bearing reaches its maximum height 21 seconds after being launched (t = 21 s).
So, the value of is .
