Answer:
25%
Step-by-step explanation:
The formula for finding change over time
P= N-O/O times 100
P= percent
N= new value (for this problem 40)
O= old value (for this problem 32)
100 to get the percentage
First, subtract 32 from 40 to get 8.
Then, divide 8 by 32 to get 0.25
Lastly multiply by 100 to get 25 which is your percentage of change
m = 13
Given
m - 5 = 8 ( isolate m by adding 5 to both sides of the equation )
m = 8 + 5 = 13
The answer is 254.47 ft
V=pi×r^2×h
pi=3.14
r=d/2
r=6/2=3
v=(3.14)×3^2×9
=254.47 ft
