The percent change from 36 to 63 is 63/36=1.75 (multiply by 100 to get a percentage) 175%
The percent change from 63 to 36 is 36/63=0.571=57.1%
First you find the area of both circles... The smaller one is Pi, and the other one is 1.75pi. Take 1.75pi and multiply it by 13, getting 22.75pi. Do the same for the other circle, getting 13pi. Now subtract the former number by the latter number, getting 9.75pi, and that is the volume.
Some examples are:
1.22
5.51
6.64
-4.11
Basically all you need to do is have 2 of the same digit next to each other.
Answer:
It would be the 2nd one
Step-by-step explanation:
Answer:
It was difficult reading the question, as written. Check my assumptions.
Step-by-step explanation:
"five more than the product of two and a number,
decreased by seven"
---
Let the "number" be a.
We are told "five more than . ." means +5,
"the product of two and a number" means 2a,
"decreased by seven" mean -7
Put the statements together to obtain:
+5+2a-7
Simplify to 2a-2
Evaluate when a = 8:
2a-2
2(8)-2
16-2
= 14
