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.
Circumference of circle with twenty four cm radius?
A circle with a radius of 24 cm has a circumference of 150.8 cm
What is the circumference of a twenty inch diameter circle?
circumference = 2 * pi * r ----> pi is a constant in this case circumference = 2 * 3.142 * 10 ------> radius is 1/2 of a diameter So, circumference of this circle is 62.84 inches
How do you find the radius of a circle when the circumference of the circle is twenty four pi?
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2π) = 24π ÷ 2π = 12 units.
To the nearest hundredth what is the circumference of a circle with a radius twenty two?
138.23
What is the circumference of a twenty four inch diameter circle?
Circumference = 24*pi = 75.398 inches to 3 dp
If A chord twenty four inches long is five inches from the center of a circle what is the radius?
nbvhfvnkjfsdbvyhfndjvnbfyuv r = 4
What is the radius of a circle with a circumference of twenty-six point six nine meters?
Radius = 26.69/2*pi = 4.248 meters rounded to 3 decimal places
What is the circumference of a circle with a diameter of twenty feet?
The circumference of a circle with a diameter of 20 feet is: 62.83 feet (diameter x Pi = circumference).
What is the circumference for twenty one feet?
If that number is the diameter of a circle, the you can multiply it by pi to get the circumference.
What is the diameter of a circle with a circumference of twenty seven feet?
Circumference of a circle is given by 2πr. Circumference(c) = 2πr = (2r)π = dπ [ r is radius and 2r = d (diameter) ] So circumference of a circle is also given by dπ. We have, c = 27 feet So, dπ = 27 feet d = (27/π) feet = 8.594 feet So the diameter of the circle = 8.594 feet.
What is the area of a circle if the radius is twenty-one?
A circle with a radius of 21 units has an area of 1,385.44 square units.
What is the circumference of a circle twenty feet around?
20 feet
