What is the square footage of a 6 foot flat circle?
To find the Square Footage of a 6 foot circle (flat), we must use the equation for Circle Area:Circle Area = pi × r2Since we know that Diameter = 6 feet we Therefore know that Radius = Diameter/2 = 3 feet = rSo, Since, the constant pi = 3.14159 (approximate), we now have all the numbers to put into our Circle Area equation:Square Footage of a 6 foot flat Circle = 3.14159 x 32= 3.14159 x (3 x 3)= 3.14159 x 9= 28.27431Therefore:The Square Footage of a 6 foot Flat Circle = 28.27431 Square Feet (Feet2)
If the length of one board is 2 feet 10 inches and the length of another board is 1 yard 1 foot 9 inches what is the total length of the two boards put together?
There are 3 feet in a yard and 12 inches in a foot. Convert all boards to the smallest unit (inches) 2 ft 10 inches = 34 inches 1 yard 1 foot and 9 inches = 57 inches 34 +57 = 91 inches, ( or 7 feet 7 inches), (or 2 yards 19 inches), ( or 2 yards 1 foot 7 inches)
