Help from all the math wizards (and wannabes) please

I need to know the area (in square feet) of a circle with a circumference of 1/3 mile.

246,499.3 square feet.

I think. Divide 1/3 by pi to get diamter ( 0.106103385 miles). Divide by 2 to get radius (0.053051693). pi * r^2 = area ( 0.008841949 square miles). convert from square miles to square feet (one statute mile is 5,280 feet, so 27,878,400 square feet per square mile gives 246,499.3 square feet). Does that sound right to everybody?

And Kallend better not give me any shit about ignoring significant figures.

Yip exactly what I got :)

Looks good to me. I'll double check after I get some sleep.

I'm getting:

3.14159*(5280/6)^2= 2,432,847.3 ft^2

The other answers do not have the formula written correctly.

No, the earlier posts are correct. It's 246,199 ft^2.

Since it's starting with a circumference of 1/3 miles which is 1760ft. The equation for circumference is C=2r*pi. Solve for radius, r. r=C/(2*pi). And use this in the equation for area: A=pi*r^2, which is with the r substitution: A=pi*(C/(2*pi))^2

Whoops- I misread the original post. I thought it said the D was 1/3 mile, not a C of 1/3 mile.

I though that looked like a strange discrepency- a full order fo magnitude off. My bad.
