Answer:
233.75
Step-by-step explanation:
if 220 is 100% of the number we need to know how much 6.25% is so we would multiply 220 and 6.25 together then divide by 100 and we would get 13.75, so 13.75 id 6.25% of 220. We would then add 220 and 13.75 together and get 233.75
4pi
The derivative of 4pi is zero,0.
It is zero because in the problem which is simply 4pi there is no variable. Thus, its derivative is zero.
