area of a circle= pi * r^2 but in this case we have diameter instead of radius

5. anonymous

yea im right

6. Godlovesme

we can find the radius by dividing the diameter by 2 r= 16/2 = 8 A= 3.14 * 8^2 A= 3.14 * 64 A= 200. 96

u used an online calculator

8. Godlovesme

how did we get a different answer o_O

9. anonymous

me

10. anonymous

which one right ?

12. anonymous

look first you have to find the formula right

13. Godlovesme

the formula is area = pi * r^2

It just depends on how they want you to write it/what to use for pi. You could write the answer as $$64\pi$$, $$200.96$$, or $$201.06$$ depending on what you use for pi.
