There is this one paper that has been bugging me for a while now. I don't exactly understand what I am getting wrong on some certain things. The ones I need help with are 4-8. Only a few questions. Please... I really need help with this. It would be so appreciated if you could help me!

Area is πr^2, right?
So,
#4. π5^2=25π
#5. 20 is the diameter. 20/2=10. π10^2. π100. 100π.
Circumference is dπ .
#6. 18π
#7. 13*2=26. 26π
#8. The formula for area is πr^2. So if the area is 144π,
Square root of 144=12. Answer is 12 meters.
Have fun on your math!
