The first one u circled is a single rotation
Hello! What type of work is that so I can specifically know! :)
Answer:
Step-by-step explanation:
30 is half or 60
45 is half of 90
1:2 ratio
<h3>Exact
Answer: (160/3)pi</h3><h3>Approximate Answer: 167.47</h3>
The approximate answer results when you use pi = 3.14, and this approximate answer is rounded to two decimal places
note that (160/3)pi is the same as 160pi/3
========================================================
Work Shown:
r = radius = 4
h = height = 10
V = volume of cone
V = (1/3)pi*r^2*h
V = (1/3)pi*4^2*10
V = (160/3)pi exact answer
V = (160/3)*3.14
V = 167.46666....
V = 167.47 approximate answer rounded to two decimal places
Since they are complementary angles, then the sum of the measure of both angles is 90
So, M/_5 + m/_6 = 90
13+ X = 90
x=77
measure of angle 6 is 77
