What is the approximate difference in the circumference of a circle with a radius of 4 ft and the circumference of a circle with a radius of 6 ft?

12.57 ft

Step-by-step explanation:

Circumference of circle with radius of 4ft.

= π * radius * 2

= 22/7 * 4 * 2

= 25.14 ft

Circumference of circle with radius of 6ft.

= 22/7 * 6 * 2

= 37.71 ft

Difference = 37.71 - 25.14

= 12.57 ft

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
