If the diameter of a circle with a circumference of 22.75 inches is doubled, what would be the circumference of a new circle

Let's solve this probem in general, to understand the underlying concept.

The circumference of a circle, knowing its radius, is given by

So, if the radius is doubled, we map and the circumference becomes

So, if you double the radius, the circumference doubles as well, and so it becomes

146%

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
