Answer:
Step-by-step explanation:
You must apply the following formula for calculate the lateral area the regular pyramid:
Where p is the perimeter of the base and l is the slant height:
Find the apothem of the hexagonal base:
Where s is the side length and n is the number of sides the polygon.
Then:
Apply the Pythagorean Theorem to find the slant height:
The perimeter is:
Susbtituting values, you obtain:
The area of a circle is πr^2
Area formula for the white region is π6^2
π6^2 = 36π
Subtract the area of the white region from the combined area
100π - 36π = 64π
