Answer:
D : 3456
Step-by-step explanation:
Use the formula 'volume of a cylinder' which is V = πr^2h
Since you know that the diameter is 20m and you need the radius, the radius is half the diameter, 10m. The height would be the length of the cylinder which is 11m.
Hence π10^2(11). If you put that in the calculator you get 3455.75, round it up and you 3456, answer D
What is the surface area of the solid?
The sum of the area of all of the faces or surface that enclose the solid.
Answer:
24 ft cubed
Step-by-step explanation:
The volume of a rectangular prism is denoted by the formula: 
, where 
is the length, w is the width, and h is the height.
Looking at the diagram, we can see that the length is 2 ft (so = 2), the width is 4 ft (so w = 4), and the height is 3 ft (so h = 3). Now, we can just plug in these values to find V, the volume:
Thus, the answer is 24 ft cubed.
Hope this helps!
