Answer:
D. AB/CE = ED/BC
Step-by-step explanation:
In this question you apply the side-Angle-side similarity property that makes the two right triangles similar.
In this property, the lengths of the corresponding legs of the two right triangles are proportional.
Hence
Leg AB corresponds to leg CE
Leg ED corresponds to leg BC
From the property;
Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20 = 62.831 in
