Surface area of the cylinder = 816.4 sq. ft.
Solution:
Height of the cylinder = 21 ft
Diameter of the cylinder = 10 ft
Radius of the cylinder = 10 ÷ 2 = 5 ft
Use the value of
= 3.14
Surface area of the cylinder = 
Substitute the given values in the surface area formula, we get
Surface area of the cylinder 

ft²
Hence the surface area of the cylinder is 816.4 sq. ft.
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
