If the area of a circle is about twenty-eight square inches what is the diameter?
If the area of a circle is about 28 square inches the diameter is: about six inches (5.971).
How many square feet in a twenty four inch diameter circle?
The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
What is the circumference of a twenty-five foot diameter circle?
The formula is C = Pi x D where Pi = 3.1416 and D is the diameter. Using the formula: C = 3.1416 x 25 = 78.54 ft
What is the circumference of a circle with a diameter of twenty one feet?
65.97344572538565800766 feet +/- Circumference = Pi x diameter 21 feet x 3.14159265358979323846 = 65.97344572538565800766 feet Of course Pi goes on for many many decimal places so the best we can do is round it off to a point we are satisfied with. Let's call it 65.97 feet.
If the central angle of a circle is twenty degrees and the radius is fifty centimeters what is the arc length?
20/360=arc length/2pi*50; 1/12=arc length/100pi. 100pi/12=arc length. arc length=25pi/3 centimeters, which is approximately 26.17993878 centimeters.
