What is the diameter of a circle with a circumference of 81m?
Diameter = 81/pi = 25.78310078 m
Circumference of a circle with radius 9 inches?
r2*pie=circumference 9(9)*pie 81*pie 254
Which is greater a rectangle with a perimeter of 36 meters or a circle with a circumference of 36 meters?
The circle has the greater area. For a perimeter/circumference of 36 metres, Area of circle = 103.13 sq metres (approx) Area of 9*9 square = 81 sq metres Area of an L*(18-L) rectangle (L < 9 metres) = anything between 0 and 81 sq metres.
What is the circumference of a 81 cm?
The circumference = 2 x r x pi If your diamter is 81cm then your circumference is 254.5cm If your radius is 81cm then your circumference is 508.9cm
If a circle has circumference of 81 meters what is its diameter to the nearest meter?
The diameter, rounded to the nearest meter, is: 26 meters(25.7831008 meters).
What is the circumference of a circle if diameter is 162 cm?
A circle with a radius of 81 cm has a circumference of 508.94 cm
What is the circumference of a circle with an area of 81 pi square centimeters?
The circumference is 56.55 cm
What is the diameter of a circle with a circumference of 81m?
Diameter = 81/pi = 25.78310078 m
Circumference of a circle with radius 9 inches?
r2*pie=circumference 9(9)*pie 81*pie 254
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)
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 if the area is 81 pi square feet?
If: pi*radius2 = 81*pi sq ft Then: radius = 9 feet Circumference = 2*pi*9 = 56.549 feet rounded to 3 decimal places
Which is greater a rectangle with a perimeter of 36 meters or a circle with a circumference of 36 meters?
The circle has the greater area. For a perimeter/circumference of 36 metres, Area of circle = 103.13 sq metres (approx) Area of 9*9 square = 81 sq metres Area of an L*(18-L) rectangle (L < 9 metres) = anything between 0 and 81 sq metres.
What is the degree of 81?
An angle of 81 degrees is an acute angle
What is the distance around a circle with a diameter of 18 inches?
The distance around a circle is called the circumference. The formula for the circumference of a circle is C = πd, where C is the circumference, d is the diameter, and π is approximately 3.14159. For a circle with a diameter of 18 inches, the circumference would be C = π(18) = 56.5487 inches.
What is the circumference of a 81 cm?
The circumference = 2 x r x pi If your diamter is 81cm then your circumference is 254.5cm If your radius is 81cm then your circumference is 508.9cm
If a circle has circumference of 81 meters what is its diameter to the nearest meter?
The diameter, rounded to the nearest meter, is: 26 meters(25.7831008 meters).
