Answer:
.375
Step-by-step explanation:
Formula for volue of cylinder is area time height. Lets find area
A=
diameter=2r
8=2r
r=4
Now substitute r to
A=
Now we have formula
V=
- its the result, so B
Answer:
ratio
Step-by-step explanation:
by using a conversion factor and a fraction, a ratio can be created to convert one unit to another.
Answer:
y=-3x-2
Step-by-step explanation:
so the line is going down so we know that the slope is going to be negative.
slope is y over x and it looks like every time it goes up 3 and to the right 1 so 3/1 is 3 so the slope is 3 and if the slope has to be negative than the answer is the first one
I assume the solid is a "regular hexagonal prism", by which it means that the cross section is a regular hexagon with all sides and angles equal.
Also, the exact apothem is 9.5262... but we will adopt the given value of 9.5.
First lateral surface area
A1=6*side length*height=6*11*20=1320 units
Then the end areas
A2=2 faces * 6 triangles/face * [base * height (apothem) /2]
=2*6*11*9.5/2
=627 units
Total area=1320+627=1947 units
