If W=20 put it in for W, Same with all the other letters: so now we have: 20+1/23+1/19+1/28. Now divide: 1/23=.043, 1/19=.053, 1/28=.036... Now add: 20+.043+.053+.036=20.132. The answer is 20.132 :)
3r = 10 + 5s , <span>r = 10
plug in the value of "r" into the equation:
3(10) = 10 +5s
30 = 10 + 5s
subtract 10 from both sides:
20 = 5s
divide both sides by 5:
4 = s
s = 4</span>
The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
L (arc) = (Angle / 360) x 2πr
Substituting the known values,
L (arc) = (40 / 360) x 2π(8 inch) = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.
