Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
Answer:
m=8+3n
Step-by-step explanation:
Move all terms that don't contain m to the right side and solve.

Hey there!
I'm assuming your expression is actually

. If it's not, let me know and I'll be happy to help you out further.
If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following:





You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9.
Hope this helped you out! :-)
