Radius = 1/2 of the diameter = 46 inches.
2*23 = 46 cm
The formula is: circumference = 2 x pi x radius. As always when you use a formula, plug in the values you know and solve for the ones you don't. So plug in 46 for the circumference and solve for the radius. (You'll get that the radius = (circumference)/(2pi)).
As area = pi * radius2, the radius is given by radius = sqrt(area /pi) radius = sqrt(6644.24 / pi) = 46 with pi = 3.14
Polaris is approx 46 times the radius of the sun: somewhere between 30 and 34 million kilometres.
its alredy out enjoy
diameter = double the radius = 48 cm
you do something to get the answer
