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
A 31-inch balloon would have a diameter of 31 inches when fully inflated. This means the width of the balloon, from one side to the other, would be approximately 31 inches.
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
To find the diameter from the circumference, you can use the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Rearranging the formula gives ( d = \frac{C}{\pi} ). For a circumference of 31 inches, the diameter is approximately ( \frac{31}{3.14} ), which is about 9.87 inches.
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.
