Answer:
.04
Step-by-step explanation:
She should have multiplied 160 by .04 and add what the product is to the original number (160*.04 = 6.4 ; 160 + 6.4 = 166.4)
Answer:
Step-by-step explanation:
We can note a couple of relationships in this circle.
The arc length will be a fraction of the circumference. It will be the same fraction of the circumference that the central angle is to the entire circle.
<u>First step: Find the circumference of the circle</u><u>.</u>
The circumference of any circle can be defined by the formula , where r is the radius of the circle. The radius is given to us, 30 in. We can now substitute that into the formula.
So our circumference is 60π.
<u>Second Step: Find the ratio of the central angle of the arc to the total circle degrees</u>
We know that the total amount of degrees in a circle is 360°. Therefore, we can set up a proportion to find the ratio between the central angle (90°) and the total circle measurement.
<u>Third Step: Equal out the two proportions and solve for the missing arc length</u>
Now that we have our base proportion (), we can turn 60π into a proportion as well, leaving 60π as the denominator so we can solve for the arc length.
We can now solve for x by cross multiplying.
Hope this helped!
