If a circle has a deameter of 6 inches about how long is its circumference?
Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches
What is the circumference and area of a circle with the radius 5 inches long use 3.14 for the value of pi?
Circumference of circle: 31.4 inchesArea of circle: 78.5 square inches
If the circumference of the rim of the wheel is 27 inches how long is each spoke?
Assuming a spoke represents the radius of the circle, each one would be 4.29 inches long. When given the circumference (27 inches), the radius (spokes) is calculated using the formula r = C / 2(pi); or Radius = 27 inches / [2(3.14)].
An arc 14cm long on the circumference of a circle subtends an angle of 128degrees.What is the radius of the circle?
The radius is: 6.267 cm
What is the circumference of a 21-inch circle how can solve?
By a 21-inch circle I presume you mean that the diameter is 21 inches. So the radius is half as long, 10.5 inches. The formula for the circumference of a circle is 2 pi r, where r is the radius. Pi is about 3.14. That is accurate to 2 decimals, or 3 significant digits all together. I use that approximation because the dimension we are given has 2 significant digits. So the circumference is pi times the diameter; we multiply 3.14 by 21 inches and get 65.94. To 2 significant digits, that is 66 inches. If you meant that the radius was 21 inches, then the circumference would be twice as much, or 132 inches.

What is the circumference of a circle if it is 13 cenatmeters long?
Circumference of a circle = 2*pi*radius or pi*diameter
If the circumference of circle is 24 centimeters about how long is the radius?
The radius is 3.82 cm
A pizza has a circumference of 47.1in what is the radius?
To find the radius of a pizza with a circumference of 47.1 inches, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Rearranging the formula to solve for the radius, you get r = C / 2π. Plugging in the given circumference of 47.1 inches, you get r = 47.1 / (2 x 3.14159) ≈ 7.5 inches. Therefore, the radius of the pizza is approximately 7.5 inches.

What is the radius for 11 inches?
Oh, dude, the radius of a circle is just half of the diameter, so for an 11-inch circle, the radius would be 5.5 inches. Like, it's just basic math, nothing to lose sleep over. So yeah, the radius is 5.5 inches, but who's really measuring, right?
If the radius of a circle is 7 inches long what is the length of the diameter of the circle?
14 inches.
What is the circumference is circle that is 24 meters about how long is the diameter if pie is 3?
Circumference of a circle = 2*pi*radius or diameter*pi Its diameter = circumference/pi
