The area is 9 feet. You find the square root of 81 which is 9. I want circumference, not area.
A circle with a radius of 9 feet has an area of 254.47 square feet.
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
A circle with a radius of 9 feet has an area of 254.47 square feet.
Area of circle: pi times 9 squared = 254.469 square feet rounded to 3 decimal places
A circle with a diameter of 14 feet 9 inches has an area of: 170.87 square feet.
Area(A)/ Area(B) = pi*rA2/pi*rB2 = rA2/rB2 = 16/81
The radius is 9 feet.
Area of circle: pi times 9 squared = 254.469 square feet rounded to 3 decimal places
If the area is square than we just find the square root of 81,which is 9 feet x 9 feet.Or if it is a Rectangle we could divide 81 by 18 to get 18 feet x 4.5 feet.If the area is a circle we will multiply 81 by PI, then take the square root multiplied by two. In that case it would equal a circle 10.1 feet in diameter.If the area was a triangle the dimensions could be 9 feet by 18 feet by 20.1 feet (altitude, base, hypotenuse).
The surface area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For an 18-foot circle, the radius is 9 feet (half of 18 feet). Plugging this into the formula, the surface area is ( A = \pi (9)^2 ), which equals approximately 254.47 square feet.
A circle with a diameter of 9 feet has a perimeter of 28.3 feet.
