Answer:
second option
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the base radius and h the height )
Here diameter = 5, so r = 5 ÷ 2 = 2.5, then
V = π (2.5)²h

Answer:
the surface area should be 544 (whatever the unit is)
Step-by-step explanation:
You start by taking the rectangles on the side and finding their area.
1. (10×14)×2 ←Because there are two rectanglular sides.
2. find the area of the triangles on the side. 1/2bh = area of triangle.
(.5×8×6)×4 ← in order to find the area for all of the triangles.
3. lastly take the base of the prism and find the area then add the previously found values together.
(12×14)+(.5×8×6)×4+ (10×14)×2 = 544
