Answer:
Step-by-step explanation:
In this case, it is 8.95. Step 2: Square the radius that you get. In this case, the answer is 80.1025.

To find the simple interest, we multiply 600 × 0.04 × 1.5 to get that:
The interest is: $36.00
        
             
        
        
        
<h3><u>Given Information :</u></h3>
- Length of parallel sides = 60 ft and 40 ft
 - Height of the trapezoid = 30 ft
 
<h3><u>To calculate :</u></h3>
<h3><u>Calculation :</u></h3>
As we know that,

- a and b are length of parallel sides.
 - h denotes height.
 
<em>S</em><em>u</em><em>b</em><em>s</em><em>t</em><em>i</em><em>t</em><em>u</em><em>t</em><em>i</em><em>n</em><em>g</em><em> </em><em>valu</em><em>es</em><em>,</em><em> </em><em>we</em><em> </em><em>get</em><em> </em>:
 Area = 
 × ( 60 + 40 ) × 30 ft
 Area = 
 × 100 × 30 ft
 Area = 1 × 100 × 15 ft
 Area = 100 × 15 ft
 <u>Area = 1500 ft</u>
Therefore,
- Area of the trapezoid is <u>1500 ft
</u>
