If a diameter intersects a chord of a circle at a perpendicular, what conclusion can be made?

The diameter and the chord are congruent.
The diameter is twice as long as the chord.
The chord is bisected.
The diameter is bisected.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

whaere is the picture
