Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term
, is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... (
)
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation.
is pretty close to 3.14.
160
3.14 = 502.4, which is decently close to our other answer.
Hope this helps!

Answer:
Step-by-step explanation:
The area of a sector in terms of radians as opposed to degrees is

Filling in the formula accordingly gives us

The radians cancel out, the pi's cancel out, the 2 in the denominator cancels out (divides into 2-squared once), leaving us with
A = 1.75(2) so
A = 3.5 units squared
Opposite sides are parallel
Opposite angles are congruent
Opposite sides are congruent.
