Answer: S1:E7 ; S2:E1 ; S3:E5
Step-by-step explanation:
What we know:
- 3 answers apply
- We need to find which answers go with each question
**A lot of info is problem-specific.
How to solve:
Since we only need to write the equations, we simply need to find the x and y variables, and the total.
Process:
Problem 1:
- Find the x 5.50
- Find the y 3
- Find the total 145
- Write equation 5.50 + 3 = 145
Problem 2:
- Find the x 2.50
- Find the y 0.75
- Find the total 25
- Write equation 2.50 + 0.75 = 25
Problem 3:
- Find the x 2
- Find the y 5
- Find the total 50
- Write equation 2 + 5 = 50
Solution: S1:E7 ; S2:E1 ; S3:E5

d/2=r
big diameter=20.4, so radius i 20.4/2=10.2cm
small is 10.8/2=5.4
so

pi10.2^2-pi5.4^2
pi(104.04-29.16)
pi(74.88)
using 3.14=pi
