Answer:
9/32 inch diameter pin will not fit into a reamed hole with a diameter of 0.278 inch
Step-by-step explanation:
Diameter of reamed hole = 0.278 inch
Radius of reamed hole = ![\frac{0.278}{2} =0.139](https://tex.z-dn.net/?f=%5Cfrac%7B0.278%7D%7B2%7D%20%3D0.139)
Surface area of reamed hole = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Surface area of reamed hole = ![3.14 \times (0.139)^2](https://tex.z-dn.net/?f=3.14%20%5Ctimes%20%20%280.139%29%5E2)
Surface area of reamed hole = 0.06066794
Diameter of pin = ![\frac{9}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B32%7D)
Radius of pin =![\frac{9}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B64%7D)
Surface area of pin = ![\pi r^2 = 3.14 \times ( \frac{9}{64})^2=0.0620](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%3D%203.14%20%5Ctimes%20%28%20%5Cfrac%7B9%7D%7B64%7D%29%5E2%3D0.0620)
Since the surface area of pin is more than the surface area of hole .
So, a 9/32 inch diameter pin will not fit into a reamed hole with a diameter of 0.278 inch

Step-by-step explanation:
(-4,0) & (6,8)
its postive when the lines are above the X axis
Answer:
the lines are perpendicular
Step-by-step explanation:
David reads 80 pages every day.
Karen reads 25% more pages every day than David reads.
So, Karen reads
more pages. She reads a total of 80 + 20 =100 pages.
Rick reads 35% fewer pages per day than Karen. So, Rick reads
less pages than Karen. He reads 100 - 35 =65 pages
So, in total the tree friends read = 80+100+65=245 pages.
So, equation becomes ![245d=10000](https://tex.z-dn.net/?f=245d%3D10000)
