Answer:
V = 1815 pi units ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = pi ( 11)^2 * 15
V = 1815 pi

Step-by-step explanation:I can’t see the question very well
Answer:
I think itsa 4 x 155 = 620
Step-by-step explanation:
2x+9y=-30 subtract 2x from both sides
9y=-2x-30 divide both sides by 9
y=-2x/9-30/9
So the slope of the reference line is -2/9. For a line to be perpendicular to this line their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1 and in this case:
-2m/9=-1
m=9/2
m=4.5, so far we have:
y=4.5x+b, using point (-8, 0) we can solve for b
0=4.5(-8)+b
0=-36+b
36=b, so our line is:
y=4.5x+36
Answer:
Step-by-step explanation:
Let Jire's age = x
Pamela's age = x - 12
Sum of their ages = 28
x + x - 12= 28
2x - 12 = 28
2x = 28+12
2x = 40
x = 40/2
x = 20
Jiri's age = 20 year
