Answer:
True
Step-by-step explanation:
The formula for the circumference of a circle is:
C=2πr
So we can substitute in the numbers we have:
Radius=4, so:
C=8π (we multiplied the radius by 2)
So the statement is true.

Answer:
True
Step-by-step explanation:
The circumference (C) of a circle is
C = 2πr ← r is the radius
For C = 8π, then
2πr = 8π ( divide both sides by 2π )
r = 8π ÷ 2π = 4
Hence the radius must be 4
