The circumference of a 42-inch diameter circle is: ~131.95 inches.
It is pi*42 = 131.9 inches approx.
21 inches.
The distance around the perimeter.c=distance aroundr=The radius of a circle is the length of the line from the center to any point on its edgeD= the distance across the circlepi x diameter, or the equivalent 2 x pi x radius.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
The radius of a circle if its circumference is 42 is about 6.68
A circle with a radius of 42 feet has a circumference of 263.89 feet.
Circumference = 42 inches => radius = 42/(2*pi) = 6.68 inches (approx)
If the radius is 42 meters, then you already know the radius.
264 cm

The circumference of a 42-inch diameter circle is: ~131.95 inches.
Circumference not required, and in any case doesn't make sense for a radius of 11; it should be 69. A = pi x r x r = 121 pi = 380.12
The formula is: (130/360)*pi*42 in square meters
Circumference = Pi x d: 42 = 3.14 x 42 = 131.88 feet
Circumference = diameter*pi feet
Circumference = 42*pi feet or approximately 131.95 feet.
