so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
Answer:
The tip of the minute hand travels 20.9 inches.
Step-by-step explanation:
We are given that the minute hand of a clock is 8 inches long. And we have to find that how far does the tip of the minute hand travel as the time progresses from 12:00 to 12:25.
<u>So, firstly we will find the circumference of circle;</u>
Circumference of circle (C) = {where r is radius of circle}
= {given r = 8 inches long}
=
Now, as we know that the minute hands completes the full circle in 60 minutes, therefore, the length of the arc between time 12:00 to 12:25 represents which is of the circumference, that means;
The length of arc from time 12:00 to 12:25 =
=
= = 6.67
Now, assuming value of = 3.14; so 6.67 = = 20.9 inches (in nearest tenth)
Hence, the tip of the minute hand travels 20.9 inches.
volume of a cone = (1/3)*pi*r^2*h
180 = pi(r^2)h
180/pi(r*2) = h
Answer: Each cylinder weighs 1/40 of a ton.
Step-by-step explanation:
If we were dealing with a total of 1 ton, than we can easily see that each cylinder would be one twentieth. Because we are dealing with a total of 1/2 ton, we can now figure out that each cylinder is 1/40 tons.
