What is the circumference of a circle with a diameter of 10 in? (NO LINKS PLS)

10π or 31.4159265359

Step-by-step explanation:

Step-by-step explanation:

radius is 5

C = 2πr

C = 2(5)π

= 10π

= 31.42in

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

can i get the link to the assignment?
