Answer:
8π in
64π mm²
Step-by-step explanation:
The circumference of a circle is equal to 2πr, where r is the radius.
2π(4) = 8π ≈ 25.132
The area of a circle is equal to πr²
π(8)² = 64π ≈ 201.062

Answer:
1/3 is closer to 0 than it is closer to -1
Step-by-step explanation:
<------------------(-1)--0---(1/3)----------------->
As you can see here, 1/3 is closer to 0 than -1
Answer:
-m^2 |n|^3 sqrt(n)
Step-by-step explanation:
-sqrt( m^4n^7)
We know that sqrt(ab) = sqrt(a) sqrt(b)
-sqrt(m^4) sqrt(n^7)
The sqrt(m^4) = m^2
The sqrt(n^7) = sqrt(n^6) sqrt(n) = |n|^3 sqrt(n) We take the absolute value because if n is negative, n^6 is postive, but n^3 is negative
-sqrt(m^4) sqrt(n^7)
-m^2 |n|^3 sqrt(n)
