Answer:
72 units
Step-by-step explanation:
A circle has a circumference of 452.16
The formula for circumference of circle = 
Where r is the radius of circle
The approximate value of pi = 3.14
Given circumference C= 452.16



Divide both sides by 6.28
r = 72
So radius of the circle 72 units
Answer: provided in the explanation section
Step-by-step explanation:
This is quite simple to analyze.
we have that:
- P (passed ) = 27/63 = 3/7
- P (passed/Underclassman ) = 15 / 35 = 3/7
- Since P (passed) = P(passed/underclassman) = 3/7
⇒ The two events are equal, hence independent.

3x^3+x^2-2x^1 that's the answer
A quadratic equation is a polynomial with an order of two. Its general form is ax² + bx + c = 0. From the choices given, the first option seems to be the quadratic equation. Simplifying the equation gives 6x² + 18x + 27 = 0.
