The diameter of any circle, including that one, is double (two times) its radius.
8.5
17
It is 17/2 = 8.5 cm.
circumference = pi * diameter C = pi * 2(17 cm) = 107 centimeters
Diameter = 17 inches Radius = 8.5 inches Are of circle = pi x r x r = 3.1415 x 8.5 x 8.5 = 226.97 square inches
17 Half the diameter
8.5
17
Diameter = 2 times the radius = (2 x 8.5) = 17 cm
17 cm
The radius measures from the center of the circle to the perimeter (outside), so if the radius is 8.5 cm that would make the diameter of the circle 17 cm. (8.5 cm X 2 = 17 cm)
It is 17/2 = 8.5 cm.
The diameter of a circle is twice the length of the radius. Therefore, if the radius is 4.2 cm, the diameter would be 2 x 4.2 cm = 8.4 cm.
Divide the diameter by 2, to get the radius. Then you can use the standard formula for the area of a circle.
The formula for the area of a circle is: A=∏r2Where A is the total area of the circle and r is its radiusThe diameter is twice the radius, so the radius in this case would be 17 feet.A=∏*(17)2A=∏*289A=289∏A equals about 907.46 feet
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately 3.14159), and r is the radius of the circle. In this case, since the diameter of the circle is given as 49 inches, the radius would be half of the diameter, which is 24.5 inches. Plugging this value into the formula, the circumference of the 49-inch circle would be approximately 154.06 inches.
