radius in feet = 13/(2*pi)
r = ~2.07 feet
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The circumference of a circle with a 13-inch radius is: 81.68 inches (r x 2 x pi = circumference).
It is: 2*pi*13 cm
The circumference is about 81.7 feet.
The circumference is about 81.7 feet.
radius in feet = 13/(2*pi)
r = ~2.07 feet
The circumference of a circle with a radius of 13 is: 81.68 units.
2*pi*radius = circumference 2*pi*radius = 13 Making the radius the subject of the formula is: radius = 13/(2*pi) = 2.06901426 feet Check: 2*pi*2.06901426 = 13 feet
radius = 2.069
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The circumference of a circle with a 13-inch radius is: 81.68 inches (r x 2 x pi = circumference).
2 x 13 x pi = 81.68 Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 2*pi*13 = 81.68140899
Circumference of a circle = 2*pi*radius or pi*diameter
