5 0

Answer:

201.06 or 200.96

Step-by-step explanation:

Use the first answer if you were asked to answer with π and use the second one if you were asked to use 3.14 if your teacher didn't specify use the first one.

To find the area of a circle you use π r² or π multiplied by the radius squared the diameter (which is what we are given) in this case is 16" so you would divide it by two giving you 8 then square 8 giving you 64 and then do π64 or π(8²). A way my teacher helped us learn these equations is with a really cool song, its called The Circle Song look it up online, I hope it helps!

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
