The circumference of a circle can be found using the equation: c = 2<span>πr, where c=circumference and r=radius.
The radius of the circle is also equal to half the diameter: r = </span>
, where r=radius and d=diameter.
Plug the equation for the radius of the circle into the equation for the circumference of the circle and simplify to get an equation that relates circumference and diameter:
Now solve that equation for π (aka isolate π) to get the ratio of the circumference to the diameter:
You know that the diameter,
, so plug that into your ratio to get your answer. Remember that dividing by a fraction is equal to multiplying by the inverse of that fraction (aka the fraction flipped):
Your answer is B) <span>3C/2 = π. </span>

Answer:
i) 2x² + 4x + 7x + 14
= 2x² + 11x + 14
ii) 2x² - 5x - 12x + 30
= 2x² - 17x + 30
