Find the arc length of the partial circle.
Either enter an exact answer in terms of rt or use 3.14 for I and
units

7.5π

Step-by-step explanation:

First we should get the entire circle's circumference with 2rπ

2 * 5 * π = 10π

Now, because whats missing is a 90° arc, which is 1/4 of the circle, we can say the the rest of it is 3/4 of the circumference.

3/4 * 10π = 7.5π

3x^3-x^2+6x-9

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
