Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
Answer:
Step-by-step explanation:
This is actually pretty simple. If x= a person, then 2x is men, and x is women.
You just have to solve for x.
714=2x+x
714=3x
x=238
Then you have to multiply it back out.
Men: 476
Women: 238
I hope this helps!
If you need help with anything else, or this answer just doesn't make sense, just let me know!
The one for 9 is 15
The one for 7 is 11
The one for 1 is -1
The one for 0 is -3
N=90 you have to simplify both sides then isolate the variable :)
Square root of 30 is 5.477. So I would plot my point right in the middle of 5 and 6 on the number line
