Question

Help me with this please !

Answer 1

True

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

Answer 2

True

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.

Hope I... yeah you get it y now I've been answering your questions a lot.
