8/8
1/8 = 0.125
1+0.125=1.125
        
             
        
        
        
The area of a rectangle is calculated my multiplying the length of the rectangle and the width of the rectangle. In this case, the length (the longer side) is 70 feet while the width (shorter side) is 30 feet. Hence the area is 2,100 ft2. 
        
             
        
        
        
Ok so given the point (r, theta) 
The corresponding Cartesian point is (r*sin(theta), r* cos(theta)) you can think about this by analyzing the points on a unit circle which is a graph of a polar circle with radius 1 and angle theta
        
             
        
        
        
Answer:
h =  - r
 - r
Step-by-step explanation:
The question requires you to make h the subject of the formula. 
S = 2πrh + 2πr²
subtract 2πr² on both sides.
S - 2πr² = 2πrh - 2πr² -  2πr² 
S - 2πr² = 2πrh
Dividing both sides by  2πr
(S -  2πr²)/2πr =  2πrh/ 2πr
h =  - r
 - r
