Volume =πr²h
192π = πr²(12) // Plug the value of the volume and the height in
r² = 192π ÷ 12π // divide by 12π on both sides
r² = 16 // Simplify
r = √16 // square root both sides
r = 4

Answer: im pretty sure its 5 to the second power so the third one
Step-by-step explanation:
Answer: -1.6
Step-by-step explanation:
To find the mean add the numbers together then divide them by the number of sets
-3 + 5 + -7 = -5
-5/3 = 1.6666666666667
or -1.6 simplified.
Well with those sorts of things, there are online tools you can use. I used one from the explore learning website
Pick the rotate around origin operation, simplify the -80 to a -16 and the 45 to a 9, then take those values and place your point on the graph. Adjust the rotation tool to 90 degrees, and your new point should be on -9, -16. Multiply both numbers by 5 and your answer would be -45, -80.
