Lemur [1.5K]3 years ago

Answer:

The equation's formula:

y - y1 = m(x - x1) \\

Remember that y intercept's x coordinate=0

So:

y - 7 =    -  \frac{4}{5} (x - 0) \\ y - 7 =  -  \frac{4}{5} x \\ y =  -  \frac{4}{5} x + 7 \: or \: y =  - 0.8x + 7

Good luck!

Find the height of a cylinder with radius 13 and surface area 1470.3.
g100num [7]
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
   =5.00042...
so h is approximately 5 units :)
