Answer:
B. π
Step-by-step explanation:
If you're looking for the length of an arc, you can easily find it through the circumference. Because we know that the formula for circumference is 2πr, then we can find that it is 6π (in terms of π), using the length of XY as the radius. As given to us, the measure of angle XYZ is 60°. Since the total degrees in a circle are 360°, we can see that the arc is taking up a sixth of the entire circle. Now, because we are trying to find the length of the arc itself, using the ratio of the arc to the circle, we can do 6π÷6=π
20% of 59.99 is 11.998 so 11.99. 59.99 - 11.99 = 48. 48x4 is 192

Answer:
$4.29
Step-by-step explanation:
An easy way to do this is to move the decimal point to the left one space.
So 42.87 would become 4.287
But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.
And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
