Answer:
The slope is m=2
Step-by-step explanation:
7 - 3 = 4 in y
2 - 0 in x
4/2
Simplify
2/1 or 2
Using the diagonal dimension and the height we can solve for the diameter of the cylinder using the Pythagorean theorem.
x^2 + 9.5^2 = 19.3^2
x^2 + 90.25 = 372.49
x^2 = 372.49 - 90.25
x^2 = 282.24
x = √282.24
x = 16.8
Now we know the diamteer and height, we can calculate the volume using the formula V = pi * r^2 * h
r = 1/2 the diameter = 16.8/2 = 8.4
using 3.14 for pi
Volume = 3.14 * 8.4^2 * 9.5
V = 3.14 * 70.56 * 9.5
v = 3.14 * 670.32
v = 2104.8 cubic meters
40 miles in 30 minutes, 60 miles in 45 minutes
divide 80 by 60 (mins in a hour) then multiply that’s by the number of minutes (30,45)
