<h3>Answer:</h3><h3>Exact volume =
32pi</h3><h3>Approximate volume =
100.48</h3>
The approximate volume only applies when pi = 3.14
Use either answer, but not both of course.
===============================================
Work Shown:
V = volume of cylinder
V = pi*r^2*h
V = pi*2^2*8
V = pi*32
V = 32pi .... exact volume in terms of pi
V = 32*3.14
V = 100.48 .... approximate volume when we use pi = 3.14
Answer: 20% increase
Step-by-step explanation: It’s out of 100 and you first got 80 and then you got 100. Since it’s out of 100 you could just subtract to numbers ex: 100-80=20. The answer is 20% increase
Problem: Maria baked 50 cupcakes for a bake sale, 29 of the cupcakes were sold, then she baked more cupcakes and then sold 52 and had two leftover cupcakes. How many cupcakes did she bake the second time?
Solution: 50 - 29 + a - 52 = 2
50 - 29 =21...(and etc.)
Hope this helps! :)
