Answer:
3 and 7
Step-by-step explanation:
For problems like these I take the largest number in this case 10, and start writing out what 2 numbers would give me 10. 0+10, 1+9, 2+8, 3+7...while doing that I subtract the numbers as well. thus 3+7=10 3-7=-4
 
        
             
        
        
        
Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r


r=35.03
Diameter is 2*radius
Diameter =  = 70.06
 = 70.06
Hence, diameter of the circle is 70.06 feet.
 
        
             
        
        
        
Divide 29.15/265 = 0.11 or 11 percent
