The radius of a circle is 4 miles. What is the circle's circumference?
r=4 mi
Use 3.14 for .

C = 39.48

Step-by-step explanation:

C = r(3.14)^2

25.13

C= 2πr = 2 · π · 4 ≈ 25.13274

Step-by-step explanation:

C= 2πr = 2 · π · 4 ≈ 25.13274

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
