Answer:
C = 30.8
Step-by-step explanation:
Circumference of a Circle:
C = 2πr
C = 2(3.14)(4.9)
C = 30.772
C = 30.8
Answer:
60π
Step-by-step explanation:
If the circle has radius of 30 units, substitute r=30 into the formula C = 2πr.
C = 2π(30)
C = 60π
Parenthasees
the first onewould evaluate to 4x²
the 2nd one would just be -2x²
