Find the radius of Circle O if DE = 12 inches and DE bisects OF.

Step-by-step explanation:

Given that,

DE bisects OF, then OB is equal to BF,

So, OB is ½r

Also, DB is equal to BE, so BE = DB = 6 in

So, applying Pythagoras theorem to triangle OBE

OB² + BE² = OE²

(½r)² + 6² = r²

¼r² + 36 = r²

Multiply through by 4

r² + 144 = 4r²

144 = 4r² - r²

144 = 3r²

r² = 144 / 3

r² = 48

r = √48

r = √16×3

r = 4√3 inches

r = 6.93 inches.

So, the radius of the circle is 4√3 inches

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
