Answer:
Figure obtained - Cylinder
Surface area of the cylinder is 1224π square units.
Step-by-step explanation:
When a rectangle is rotated about an axis along its largest side, a cylinder having radius 17 and height 19 units is formed.
Surface area of the cylinder = 2πr(h + r)
By substituting r = 17 units and h = 19 units in the given formula,
Surface area = 2π(17)(17 + 19)
= (34)(36)π
= 1224π
Therefore, surface area of the cylinder is 1224π square units.
Answer:
Slope: ![-\dfrac{1}{2}](https://tex.z-dn.net/?f=-%5Cdfrac%7B1%7D%7B2%7D)
Equation: ![y=-\dfrac{1}{2}x+8](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B1%7D%7B2%7Dx%2B8)
Step-by-step explanation:
The line of the best fit passes through the points (0,8) and (4,6).
If the line passes through the points
and
then the slope of the line is
![\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Hence, the slope of the line of the best fit is
![\dfrac{6-8}{4-0}=\dfrac{-2}{4}=-\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B6-8%7D%7B4-0%7D%3D%5Cdfrac%7B-2%7D%7B4%7D%3D-%5Cdfrac%7B1%7D%7B2%7D)
The equation of the line is
![y=mx+b,](https://tex.z-dn.net/?f=y%3Dmx%2Bb%2C)
where m is the slope and b is y-intercept, so the equation of the line of the best fit is
![y=-\dfrac{1}{2}x+8](https://tex.z-dn.net/?f=y%3D-%5Cdfrac%7B1%7D%7B2%7Dx%2B8)
