Así dial has a circular base with a diameter of 90 feet as show in the diagram which measurement is closer to the area of the circular base in square feet

The formula for calculating the area of a circle is A = πr², where r is the radius of the circle. In this case, the diameter of the circular base is given as 90 feet, so the radius would be half of that, which is 45 feet.

Plugging this into the formula, we get:

A = π(45)²
A = π(2025)
A ≈ 6361.73 square feet

Therefore, the measurement that is closer to the area of the circular base in square feet is 6361 square feet.
