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.
What is the circumference of a circle with a diameter 40 FEET?
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given a diameter of 40 feet, we can plug this value into the formula to find the circumference: C = π(40) = 3.14159(40) = 125.6636 feet. Therefore, the circumference of a circle with a diameter of 40 feet is approximately 125.66 feet.
If the diameter of a circle is dilated by a scale factor of 0.6 what will be the effect on the circles circumference?
When a circle's diameter is dilated by a scale factor of 0.6, the new diameter will be 0.6 times the original diameter. Since the circumference of a circle is directly proportional to its diameter by the formula C = πd, where C is the circumference and d is the diameter, the new circumference will also be 0.6 times the original circumference. Therefore, the effect of dilating the diameter by a scale factor of 0.6 will be a decrease in the circle's circumference by 40%.
What is the circumference of circle with 40 foot diameter?
By definition pi is the ratio between the circumference and the diameter pi=C/D so C=pi*D and C=pi*40=125.6 (if pi=3.14)
What is the diameter of a 40 foot circumference?
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
