Answer: 13%
Step-by-step explanation:
We know that the formula to find the simple interest :
, where P is the principal amount , r is rate (in decimal )and t is the time period (in years).
Given : Albert borrowed $19,100 for 4 years. The simple interest is $9932.00. Find the rate.
i.e. P = $19,100 and t= 4 years and I = $9932.00
Now, Substitute all the values in the formula , we get
![9932=(19100)r(4)\\\\\Rightarrow\ r=\dfrac{9932}{19100\times4}\\\\\Rightarrow\ r=0.13\ \ \ \text{[On simplifying]}](https://tex.z-dn.net/?f=9932%3D%2819100%29r%284%29%5C%5C%5C%5C%5CRightarrow%5C%20r%3D%5Cdfrac%7B9932%7D%7B19100%5Ctimes4%7D%5C%5C%5C%5C%5CRightarrow%5C%20r%3D0.13%5C%20%5C%20%5C%20%5Ctext%7B%5BOn%20simplifying%5D%7D)
In percent, 
Hence, the rate of interest = 13%

<u>CIRCUMFERENCE</u></h2>
<h3>Possible Question:</h3>
» The diameter of a circle is 11 in. What is the circle's circumference?
<h3>Answer:</h3>
— — — — — — — — — —
<h3>Step-by-step explanation:</h3>
To find the circumference, use pi (π), a mathematical constant. Its value is approximately equal to 3.14.
— Multiply the diameter with π in order to get the circumference of a Circle.
Therefore, the circumference of the circle is 34.54 inches.
