How many acres in area with 2750 meter radius?

Answer 1

First you need some conversion units, you could either convert meters to feet, or you can use the following conversion I'm providing:

1 acre is about 4050 square meters.

Then you need to know Area =π

r2

So, Area =π(2750 m)2 = 7 562 500

π m2

(7 562 500

π m2) ( 1 acre / 4050 m2 ) ~= 1867

π Acres ~= 5866 acres

The answer is 5866 acres.

If significant figures are important, you have 3, and the answer would round to 5870 acres.
