The formula for the volume of a cylinder is V=pi*r^2*h 
Since the diameter is 6.8, the radius must be 3.4 (6.8/2)
We can then plug in the given values to solve for the volume
V=3.14*3.4^2*4
V=3.14*11.56*4
V=145.2 so B

Hope this helps

Which of the following equations describe the line shown below? 
frez [133]
Here, Slope (m) = y2 - y1 / x2 - x1
m = 10 - 2 / 1 - (-3)
m = 8 / 4
m = 2

y - 10 = 2 (x - 1)
Also, y - 2 = 2(x + 3)

In short, Your Answers would be A & B

Hope this helps!

dlinn [17]

Answer: Explanation:First, let's call the number of 2 cent coins: tNext, let's call the number of 5 cent coins: fWe can then write to equations from the information in the problem.Equation 1: t+f=40Equation 2: 0.02t+0.05f=1.55Step 1) Solve the first equation for t:t+f=40t+f−f=40−ft+0=40−ft=40−fStep 2) Substitute (40−f) for t in the second equation and solve for f:0.02t+0.05f=1.55 becomes:0.02(40−f)+0.05f=1.55(0.02×40)−(0.02×f)+0.05f=1.550.80−0.02f+0.05f=1.550.80+(−0.02+0.05)f=1.550.80+0.03f=1.550.80−0.80+0.03f=1.55−0.800+0.03f=0.750.03f=0.750.03f0.03=0.750.030.03f0.03=25f=25Step 3) Substitute 25 for f in the solution to the first equation at the end of Step 1 and calculate t:t=40−f becomes:t=40−25t=15The Solution Is:There are:15 two cent coins25 five cent coins
