Answer:

90.8

Step-by-step explanation:

cercumference=πD

r=2×D

<h2>C=2πr</h2><h2><u>c</u><u>=</u><u>2</u><u>×</u><u>π</u><u>×</u><u>4</u></h2><h3>π=22/7 or 3.14 so,</h3>

C=90.8

A hiker moves 3 meters east, which is vector A. Then the hiker moves four meters north, which is vector B. The displacement vect
Fantom [35]

Answer:

About 53.13 degrees.

Step-by-step explanation:

If we draw the path of the hiker, or rather, all three vectors with vector B having its starting point at the end point of vector A, a right triangle is formed. We will most likely be using trigonometric functions to solve this.

vector A is parallel to the x axis (West - East), and vector B is perpendicular, so we'll be using the inverse tangent function to get the angle based on the ratio of the lengths of vector B to vector A, which is \frac{4}{3}

atan(\frac{4}{3}) = 53.13 degrees.

If one would be pedantic, they'd say that the direction we have to go to get from vector C to vector A is clockwise, which is anti-mathematical, the true answer would be -53.13 degrees. Alternatively, whatever 360-53.13 is.
