What's the area of the circle with a radius of 8.5 mm

jim_thompson5910 · Answer

Use A = pi*r^2

anonymous · Answer

Do I leave pi as is or do I actually incorporate it into the answer this time?

jim_thompson5910 · Answer

well now it's saying to round to the nearest tenth, so I would go for 3.14 this time

jim_thompson5910 · Answer

or you can use your calculator's pi button to get a longer version of pi

anonymous · Answer

it's fine I'm just suppose to round my answer off at the end, but the area for the circle would be 226.980

jim_thompson5910 · Answer

good I'm getting about the same

jim_thompson5910 · Answer

now if you wanted the complete circle, you'd be done, but you don't

you only want a fraction of that area

more precisely, you want 32/360 = 4/45 of this total area

jim_thompson5910 · Answer

so multiply 4/45 by 226.980 and round to the nearest tenth to get your final answer
