<h3>The measurement of the central angle is 135 degrees</h3>
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>

Where,
r is the radius
is the central angle in degrees
From given,

Substituting the values we get,

Thus the measurement of the central angle is 135 degrees

h is no of hours
e is earnings
Answer:
23.04 miles
Step-by-step explanation:
Volume = area of base *height
20 = pir^2 *h
20 = 3,14*4*h
h = 20/12,56 = 1,59 rounded 1,6
- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that
tan ß = h/r so tan ß = 1,6/2 = 0,8
tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
