b) The surface area is 564.5. Picture below.
4. Three possibilities.
Formula for volume of a cylinder: πr^2h
Formula for volume of sphere: 4/3πr^3
If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.
I used substitution on this website https://www.omnicalculator.com/math/volume
Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.
Replace x with a couple of numbers, solve for Y them mark those points on the graph and connect with a line.
See picture:
Answer:
A. 3(y+2)
Step-by-step explanation:
B wouldn't work because it would be safe to assume that it represents the quintuple of the sum. C also wouldn't work because although the y is tripled, the 2 isn't. And D wouldn't work because it is only tripling 2.
A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.
Answer:
y=20,x=9
When doing problems like this it is important to always note: whatever you do to one side of the = sign you have to do to the other side.
Step-by-step explanation:
For this problem it helps that they already give you what y equals to so you can plug y in the top equation to figure out what x is. See attachment for step by step process
