divide 3.14 by 58 and then divide the answer by 2
13.47
18.47 inches
In order to find the diameter of a circle, you have to take the circumference of the circle and divide by Pi for which you can use the approximation: 3.14. So if the circumference of the circle is 60 inches, you divide that by Pi (3.14) and get a diameter of 19.0985 inches.
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
Diameter of a circle = circumference/pi
circumference/pi = diameter
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
a circle with circumference of 25.56 inches.
Multiply the diameter by pi to find the circle's circumference
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
In order to find the diameter of a circle, you have to take the circumference of the circle and divide by Pi for which you can use the approximation: 3.14. So if the circumference of the circle is 60 inches, you divide that by Pi (3.14) and get a diameter of 19.0985 inches.
The circumference and area of a circle with diameter of 12 inches are:C = 37.7 inchesA = 113.1 square inches
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
Multiply the diameter by Pi:8 inches x Pi (about 3.1416) = 25.1328 inches circumference
Divide the circumference by Pi.
circumference = 4*pi inches
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
Multiply it by Pi.
Multiply the diameter by Pi (about 3.1416). The result is the circumference:3 x 3.1416 = 9.4248 inches circumference
