Find the arc length of the partial circle

7pi/2

Step-by-step explanation:

If was a full, the circumference or the arc length would be 2pi*r where r in this case is 7 so it would be 14pi.

Now this only a quarter of that, so this arc length is actually 14pi/4.

This can be reduced 14pi/4 =7pi/2

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

too many. (jk)

31 v bucks

step-by-step explanation:
