The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
24 inches, because the radius is always 1/2 of the diameter.
12 inches
24*pi inches
56
Radius = diameter/2 = 24 inches
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
12 inches because the radius is always half of the diameter
The radius of a circle is always half the diameter: 48 / 2 = 24 inches.
Radius of the wheel: 24/2 = 12 inches
24 inches, because the radius is always 1/2 of the diameter.
Diameter = (2 x radius) = 2 x 12 = 24 inches
My answer is 12
2r = dIf you calculate the formula correctly, the diameter would be 24 inches.
A circle with a radius of 24 inches has a circumference of 150.8 inches.
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = pi*24 = 75.39822369 inches
area = pi x radius x radius = 3.14159 x 12 x 12 =452.4 square inches
