2.
levacccp [35]

Answer:

10

Step-by-step explanation:

Use the distance formula.

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We have x1 = 2; y1 = 0; x2 = -6; y2 = 6.

d = \sqrt{(-6 - 2)^2 + (6 - 0)^2}

d = \sqrt{(-8)^2 + 6^2}

d = \sqrt{64 + 36}

d = \sqrt{100}

d = 10

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 :)
