Solution
Step 1
We first find the circumference of the hemisphere
Circumference of a semicircle
[tex]\begin{gathered} Circumference\text{ of a semicircle = }\pi r \\ \text{Diameter = 8} \\ \text{Radius is half Diameter =4} \\ \\ Circumference\text{ of a semicircle =}3.14\times4 \\ Circumference\text{ of a semicircle =}12.56ft \end{gathered}[/tex]
Step 2
We have to sum all the outer sides
10ft + 6ft + 12.56ft
The outer perimeter of the figure is 28.56ft
