Answer 1

Do you know your formula for circumference?
\[C=\Pi d\] or \[C=\ (3.14) d\]
If the radius is 7 and the diameter is radius times two, that makes the diameter 14cm.
What do you get for the answer? :)

Answer 2

is it A

Answer 3

Yes!
(3.14) x (14) = 43.96
Which you can round to the whole number 44! Good job :)
