Answer: 28.27
Step-by-step explanation:
A=3.14r^2
A=3.14•3^2
A=3.14•9
A=28.27
volume of cylinder: π * radius² * height
=============
⇒ π * 4² * 4
⇒ π * 16 * 4
⇒ 64π
<u>Thus the volume of cylinder is 64π cm³</u>
Answer:
y=1x+2 or y=x+2
Step-by-step explanation:
We know that the slope is going to be one since the slopes of parallel lines are equal and the other equation has a slope of 1. We can then use the equation y=1x+b and the point given, (2,4), to find the y-intercept, b. You plug in (2,4) as your x and y values to get 4=1(2)+b. You can then solve this by multiplying to get 4=2+b, then subtracting 2 from both sides to get b=2. We can then use b to complete the equation as y=1x+2 or y=x+2.
