The inner and outer Radii of a cylindrical pipe are 5 cm and 4 cm respectively. find the area of cross section of the pipe.
Answer:
28.3 cm²
Step-by-step explanation:
You find the area of the whole section which is 5²π = 25π.
Then you find the area of the empty part which is 4²π = 16π.
Then you subtract to get 9π which is 28.27433388......
= 28.3 cm²
Answer:
False
Step-by-step explanation:
y=5x + 5
0=5 (5)+5
0=10+5
0≠15
False
we are given points A and B
A=(3,150)
B=(4,200)
we can find points
x1=3 , y1=150
x2=4 , y2=200
(a)
the change in y-values from Point A to Point B is
now, we can plug values
...........Answer
(b)
the change in x-values from Point A to Point B is
now, we can plug values
...........Answer
(c)
the rate of change of the linear function in feet per second is
now, we can plug values
.................Answer
The straight line graph indicates that rate of change of the distance traveled with time by the red kangaroo is a constant
Reasons:
The y-values at point A = 150 feet
The y-values at point B = 200 feet
Change in y-values from point A to point B, Δy is given as follows;
Δy = y-values at point B - y-values at point A
Δy = 200 feet - 150 feet = 50 feet
Change in y-values from point A to point B, Δy = 50 feet
The x-values at point A = 3 seconds
The x-values at point B = 4 seconds
Change in x-values from point A to point B, Δx is given as follows;
Δx = x-values at point B - x-values at point A
Δx = 4 seconds - 3 seconds= 1 second
Change in x-values from point A to point B, Δx = 1 second.
The rate of change of the linear function is , therefore, we have;
