Answer:
399.6 miles²
Step-by-step explanation:
The area (A) of the major sector is
A = area of circle × fraction of circle
= πr² ×
= π × 13.4² ×
= ≈ 399.6 miles²

What is volume?
- Volume is a measure of enthralled three-dimensional space.
- It's frequently quantified numerically using SI-deduced units or by colorful Homeric units( similar to the gallon, quart, boxy inch).
- The description of length( cubed) is interrelated with volume. The volume of a vessel is generally understood to be the capacity of the vessel; i.e., the quantum of fluid( gas or liquid) that the vessel could hold, rather than the quantum of space the vessel itself displaces.
- In ancient times, volume is measured using analogous-structured natural holders and latterly on, standardized holders.
- Some simple three-dimensional shapes can have their volume fluently calculated using computation formulas.
- Volumes of more complicated shapes can be calculated with integral math if a formula exists for the shape's boundary.
