What is the circumference of a 40 inch circle?
Circumference of any circle = 2*pi*radius or diameter*pi
What is the diameter of a circle with a radius of 20 feet?
Diameter = 2 * radius So in this case, 40 feet.
Diameter of circle in inches if the radius is 20 feet.?
40'
What is the diameter of a circle whose radius is 20 ft?
40 ft
How many square feet in a 40' diameter circle?
Area of circle: pi times radius squared
What is the circumference of a 40 inch circle?
Circumference of any circle = 2*pi*radius or diameter*pi
If the radius of a circle is 20 what is the diameter?
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.
What is the diameter of a circle with a radius of 20 feet?
Diameter = 2 * radius So in this case, 40 feet.
If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
Diameter of circle in inches if the radius is 20 feet.?
40'
If the diameter of a circle is 40 millimeters what is the length of the radius?
20 millimeters
What is the diameter of a circle whose radius is 20 ft?
40 ft
How many square feet in a 40' diameter circle?
Area of circle: pi times radius squared
How many square inches in a 40 inch diameter circle?
Area of a circle = πr² (remember that r or radius is exactly half of the diameter) Radius therefore = 40/2 = 20 inches Thus the Area = 3.14159 × 20 squared = 1256.636 square inches
How can you find the diameter of a circle with a radius of 20ft?
Double the value of the radius which in this case is 2*20 = 40 feet
Find the circumference of a circle that has a diameter of 40 in round to the nearest inch?
Twice pi multiplied by the radius will get you the result. Pi, if you are going to round to the inch, call it 3.14. The radius will be half the diameter...20 inches. Find a calculator and multiply 2 X 3.14 X 20...you can do it. You can also multiply pi times the diameter and get the same result.
Is a circle with a area of 40 more less or same than a circle with a radius of 4?
In order to even discuss this question, we must assume that the unit of the '40' is the square of the unit of the '4'. -- The radius, diameter, and circumference of the circle with an area of 40 are each 10.794% shorter than the corresponding measurement in the circle with radius = 4 . -- Its area (40) is 20.423% less than the area of the circle with the radius of 4 .
