Approx 755 square feet.
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
Multiply length x width = 527 Sq. ft.
The diameter is 31 times 2 = 62 miles
900 To calculate square footage or square meters you multiply the length by the width. 30 X 30 = 900 feet X feet = square feet OR ft2 together you get [ 900 ft2 ]
31 is a not perfect square.
Improved Answer:-Its radius: circumference/diameter = piIts area: pi*pi squared = 31 square cm rounded to nearest integer
The square root of 31 is about 5.57
It is 31 feet!
1.2 m * 2.4 m = 2.88 sq m = 31 sq feet.
The number 31 is not the square of a whole number. It is the square of 5.5678.
31 x 31 = 961 31 is the square root of 961.
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
