To Find : Which represents the empirical formula for?
Solution:
Definition of Empirical Formula - A formula that gives the simplest whole-number ratio of atoms in a compound.
To reduce it in simplest form
Divide the subscript numbers by 3
So, the resultant :
Thus the empirical formula for :
Answer:
<em>L= 9.086 feet</em>
Step-by-step explanation:
<u>Area of a Circular Sector</u>
Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by
And the length of the arc is:
We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:
Solving for θ:
The arc length is:
L= 9.086 feet
