8pi, the circumference is 2pi multiply by radius

Circumference = 2pi*r Circumference = 86pi

area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077

Radius of circle: 132/2pi = 21cm to the nearest integer

Radius of circle: 12.5/2pi = 2 units rounded

area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077

Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).

Radius of circle: 132/2pi = 21cm to the nearest integer

Radius of circle: 12.5/2pi = 2 units rounded

The circumference of a circle = pi*diametre = 2pi*radius

Radius = 22/2pi m

Radius of the circle: 25.12/2pi = 4 meters rounded

Radius of circle: 157/2pi = 25 m rounded

Radius = circumference/2pi, in this case 69/2pi or 34.5/3.14, as near 11 cm as makes no difference.

Circumference = 2pi*r 26.69/2pi = 4.248m (rounded to three decimal places)
