( c^2 )^3 = 64 <=>(  c^2 )^3 = 4^3 <=> c^2 = 4 <=> c = 2 or c = -2.
        
             
        
        
        
For this case we first calculate the rate in blocks per minutes.
 rate = (15.5) / (35) = 0.443 blocks per minutes.
 Then, we can go to blocks per hour.
 Remember: 1h = 60min.
 rate = 0.443 * (1/60) = 0.00738 blocks per hour.
 answer
 his rate in blocks per hour is 0.00738 blocks per hour.
        
             
        
        
        
Answer:
14.13 ft²
Step-by-step explanation:
The area of a semicircle is 

We were given the radius of the semicircle to be: r=3 feet.
We were also asked to use π as 3.14.
We substitute into the formula to get:

This is the same as:

Or


The area of the semicircle is 14.13 ft²
