Circumference = 2(pi)(radius)

Circle 1: 48=2(pi)(radius)
              24/pi = radius

Circle 2: 12 = 2(pi)(radius)
                6/pi = radius



Area = (pi)(radius)^2

Circle 1: A = (pi) (24/pi)^2
                  = 576 / pi

Circle 2:  A = (pi) (12/pi)^2
                  = 144 / pi

576/144 = 4 times greater

Answer:

The correct answer is choice D.

Step-by-step explanation:

Since the parabola opens sideways, that means the function will feature y^2 and not x^2, so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of y^2 is positive. Using all of this information, you'll find that the correct answer is D: x = \frac{1}{12} y^2.

What is the approximate length of RP? Round to the nearest tenth.
Nimfa-mama [501]
From the circle geometry theorem, a tangent to a circle makes 90° angles with the radius of the circle.
 
RQ is perpendicular to QP
Triangle RQP is a right-angled triangle

by Pythagoras theorem

RP= \sqrt{5.3^{2}+ 3^{2}  }=6.1 units (rounded to one decimal place)
