Answer:
90π units²
Step-by-step explanation:
(refer to attached)
Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,
= 2πrh
= 2π(3)(12)
= 72π units²
Hence,
Surface area = 18π + 72π = 90π units²

Answer:
The graph is attached.
Step-by-step explanation:
The graph of the line with the slope and the y-intercept , has the form
In our case the rate of change is ; therefore we have the equation
The graph of which is attached.

Answer:
r = 1
Step-by-step explanation:
By plugging (9,2) into the point slope formula, we get that y=1/3x-1. To reach the same formula with the point (6,r), r must be equal to 1.
It’s C x(3) then y(-4) since 3 is x it becomes 34x -4 meaning negative 4
