Answer:
In terms of pi: 164.5pi cm squared
Substituting pi for 3.14: 516.53 cm squared
Step-by-step explanation:
3.5^2 = 12.25pi
12.25*2 = 24.5pi
7pi*20 = 140pi
140 + 24.5 = 164.5pi
164.5*3.14 = 516.53
Answer: 24: 80
Step-by-step explanation: 6 can go into 24 4 times. So if we do the same for 20 it will be 20 times 4. Hence, answer is 24:80

I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40
If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.
There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60
m 10 is 180 - 78 - 60
