1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
The magnitude of a vector has to do with the vector length that is used to show the initial and final position of the vector.
<h3>What is a Vector?</h3>
This refers to the quantity that has a magnitude and direction and can be used to show position.
Hence, we can see that the vector, magnitude, and the directional angle values are not given so a general overview was given.

#SPJ1
W² - v + 1
(-2)² - (-8) + 1
4 + 8 + 1 = 13
B.13 is your answer
(two negatives = one positive)*
(plug in -2 for w, and -8 for v)
(is that w², or do you mean 2w?)
hope this helps
