Answer: 6.28 cm
Explanation: The radius of a circle is half of the diameter, therefore you divide the diameter by two to find the radius.
ab + a + 4b+4 = a(b+1) + 4(b+1) = (b +1)(a + 4)
6x-1=4x+6
Subtract 4x from each side
2x-1=6
Add 1 to each side
2x=7
Divide by 2 to isolate the variable
6(7/2)-1=21-1=19cm
