Question

How do you get the answer to these two questions? I don’t understand

Answer 1

Hey, so it's actually pretty simple I'll try my best to explain it properly!

Explanation:

So for the first blue circle the line that goes to the middle that's the radius. And to solve the area you need to know the radius. The formula to solve the area is A =
`\pi`
`r^(2)` so what we would do its 3.14 times 6 times 6 or 3.14 times 36 which would give us the area! Now for circumference, the equation for that is C = 2
`\pi r^(2)` which would look like 2 times 3.14 times 6 times 6 or 2 times 3.14 times 36 and that would give you the circumference.
