Answer:
15.7 feet
Step-by-step explanation:
What we are looking for here is the perimeter/circumference of the table. The formula for the circumference of a circle is diameter x pi. The diameter is 2x the radius so I did 5 x 3.14, 3.14 being in place for pi. Hope this helps! : )
 
        
             
        
        
        
 Answer:
Step-by-step explanation:in a regular pentagon all angles are equal that means one of the triangles angle is 180-108=72
 
        
             
        
        
        
This is the concept of applications of volume. We are required to calculate BTUs per cubic foot. This will be given by the formula:
(BTU)/volume
Total BTU=15*750=11,250
(assuming the bus is a perfect cuboid) volume of the bus will be;
volume=length*width*height
=38*8.5*6.25
=2018.75 ft^2
Thus the BTUs per foot will be:
11250/2018.75 
5.57 BTUs/ft

Answer:
   2
Step-by-step explanation:
The products of chord lengths are the same for the intersecting chords:
   AQ×BQ = CQ×DQ
   6×12 = CQ×(38 -CQ)
This gives a quadratic in CQ:
   CQ² -38CQ +72 = 0 . . . . . write in standard form
   (CQ -2)(CQ -36) = 0 . . . . . factor the quadratic
   CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero
The minimum length of CQ is 2 units. (DQ will be 36.)
