What is the arc length of a circle that has a 6-inch radius and a central angle that is 65 degrees? Use 3. 14 for pi and round y
noname [10]
C=2πr

C=2π6

C=<span>37.6991118431
</span>
That's the arc length of the whole circle, i.e. the arc length of 360°.

65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.6991118431 is 
6.8067840827819444444444444444444.  Rounded to the nearest hundredth, the answer is 6.81 inches.

That's real pi, lets see if it makes a difference to use "stupid pi".

C=2πr

C=2π6

C=37.68

That's the arc length of the whole circle, i.e. the arc length of 360°.

65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.68 is 
6.803333333333333333333333.  Rounded to the nearest hundredth, the answer is 6.80 inches.
Yep makes a difference.  That's why you don't use stupid pi.  3.14159 is what we always used in engineering, or just the pi button and using a ton of digits.

Answer: 6.80 inches.

Why is 3/4 greater thab 11/16 how can i be sure
Delicious77 [7]
You can make them have the same denominator and then compare

( \frac{3}{4}) ( \frac{16}{16}) =  \frac{48}{64}

(\frac{11}{16})( \frac{4}{4}) =  \frac{44}{64}

so as you can see, \frac{3}{4} is \frac{4}{64} bigger than  \frac{11}{16}
