Answer:

circumfrence: ≈53.40708 area:≈226.98007

Step-by-step explanation:

For area, the formula is A=πr^2, so first divide the diameter (17) by 2 to get the radius which is 8.5

square 8.5 and then multiply by pi

plug everything in to get ≈226.98007

For circumfrence the formula is πd, so multiply 17 by pi

plug everything in to get ≈53.40708
