area of a circle

I need help in computing the square foot in the area of a circle with a radius of 80 meters

π x R squared?

Busflyer · Apr 12, 2014

20,106 square meters which gives 216419.18 square feet.

Area = pi x radius squared

I came up with 20,096 sq meters. 80X80= 6400. take 6400 X 3.14 (pi) gives you 20,096.

The square footage I came up with is 216,420.88 sq.ft. Please let us know the correct answer. Thanks

I got 216,310.2387 sq ft, without rounding, which is what I did in my previous post.

1 Meter = 3.281 Feet
80 x 3.281 = 262.48 Feet
r = 262.48 feet
pi = 3.1416
Area of circle = pi x r^2
3.1416 x (262.48 x 262.48) = 216,442.889 sq ft
1 acre = 43560 sq ft
216,442.889 / 43560 = 4.9688 Acres

D^2 x .7854 = area of a circle.

160^2 x .7854 = area in sq meters.

25600 x .7854 = 20106 sq meters.

39" ^2 = 1521 inches / 144 to get sq feet =
10.56 sq feet per sq meter.

20106 x 10.56 = 212000 roughly sq feet or 4.87 acres. somebody check my math

Meters ....... schmeters ....... :!: Why measure it in meters and then convert it to feet? Just get another tape measure!

pi * (Radius squared)

3.33 ft to the meter x 80 mtr =266 ft : by 2 = 133 ft x 133 ft = 17689 ft x pi 3.14 = 55543.46 sq feet.
