Answer:
Area = 87.9646 sq. units from A = 28*π sq. units.
However I cannot see this in your answer list, since the numbers look all jumbled. Choice A. looks close to it, since there is a 28...
Step-by-step explanation:
We have a cylinder with height h = 5
radius = 2
We want the surface area of this cylinder.
A = (circumference)*h + 2*(pi)*r^2
A = ( 4*π)*5 + 2*π*(2^2)
A = 20π + 8π = 28 π square units
A = 87.9646 sq.. units

Answer:
- B: the area of the triangle GHK plus the area of triangle HIK
Step-by-step explanation:
<u>Connect points H and K and you have two triangles:</u>
<u>The answer options:</u>
statement A:
- the area of triangle GHL plus the area of triangle HIJ
- <u>False</u>. This leaves a gap (HJKL)
statement B:
- the area of the triangle GHK plus the area of triangle HIK
- <u>True</u>
statement C:
- the area of the triangle GJK plus the area of triangle ILK
- <u>False</u>. This leaves a gap and overlap.
statement D:
- the area of triangle GHK plus the area of triangle ILK
- <u>False</u>. This leaves a gap and overlap.
