What is the circumference of a circle with an area of 81 pi square centimeters?
The circumference is 56.55 cm
The area of a circle is 81 pi square feet What is the radius?
The area is 9 feet. You find the square root of 81 which is 9. I want circumference, not area.
What is the circumference of a circle with an area of 81?
In every circle . . .Area = (pi) x (radius)2Diameter = 2 x radiusCircumference = (pi) x diameterIn this circle, Area = (pi) R2 = 81R2 = 81/piR = sqrt( 81/pi )Diameter = 2 x sqrt( 81/pi )Circumference = (pi) x 2 x sqrt( 81/pi ) = 2 x sqrt( 81 pi ) = 18 sqrt(pi) = 31.9042 (rounded)
What is the circumference of a circle if diameter is 162 cm?
