The height of a cylinder is equal to the diameter of the base. what expression represents the volume of the cylinder, in cubic units?

4πx2
2πx3
πx2 + 2x
2 + πx3

The volume of the cylinder will be 2π

 

As shown in figure, R is the base radius of the cylinder.

H is the height of the cylinder.

Given: H = diameter of the base of cylinder.

Now, diameter of the base = 2R

So, H = 2R

Volume of cylinder = π××H

                                  = π××(2R)

                                  = 2 π  cubic units.

For the are of the trapezoid u would do is 1/2 (base 1 + base 2) times the height. so therefore it would be 1/2(11+17)13 and u would get 182. so 182 is your answer for that one.

for the second ine u would cut it into that small square and big square you will have to find the area of both of them and add them together. so the small one would be 5 times 4 which is 20. the second one would be 11 times 9 and that's 99 so u would add 99 and 20 and get 119 and that would be your answer

the first one is 182
the second one is 119
