The circumference of a circle is 270.04 centimeters. What is the circle's diameter?
Use 3.14 for .

86cm

Step-by-step explanation:

d= C/π

270.04/3.14 =86cm

1/5^2 = 7.56/45

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
