Answer:
Option D
Step-by-step explanation:
By the property of intersecting chords,
If two chords are intersecting at a point inside a circle, product of lengths of the line segments on each chord is equal.
DI × EI = HI × GI
12 × EI = 8 × 6
EI =
EI = 4
Therefore, Option D is the correct option.
R = 40.5 m
C = 254.46900494077 m
A = 5152.9973500507 m<span>2</span>
Each of A, C, and D are rational, so presumably B is the answer here.
A is rational, since
, so
.
C is also rational. If
, then
. This would mean
, and so
.
D is rational by a similar argument. If
, then
. So,
, which means
.
