Example 2

If the Lido Beach cabanas have a diameter of 2 metres, a wall height of 1.85 metres, and a roof slant height of 1.35 metres, determine the exposed surface area of 20 cabanas, to the nearest tenth.

Determine the radius of each cabana, identify the given values, and then substitute them into the formula determined in Example 1.


 

Example 3

Recently, a hurricane hit Lido Beach and five cabanas were completely destroyed. In addition, three others were severely damaged, each needing approximately 5.3 m2 worth of material for repairs. Two others suffered damage to their fabric doors, requiring a total of 1.5 m2 worth of material for repairs.

A local Florida company charges $80/m2 for material replacement and repairs.

Calculate the total cost of cabana replacement and repairs at Lido Beach.
