Answer:
A. 177 ft²
Step-by-step explanation:
To solve solve the area of the base, we learnt that the base is circular, so we will simply use the formula for finding area of circle to solve;
A = π r²
where r = radius
π is a constant
A= area of a circle
From the question given;
diameter is 15 ft, but radius is half of diameter, this implies that r = d/2 =15/2= 7.5 ft
π≈3.14
We can now proceed to insert our values into the formula;
A ≈ 3.14 × 7.5²
≈3.14×56.25
≈176.625
≈177 ft²
Therefore, the area of the base is 177 ft² approximately.
