A circle with a radius of 3 inches has a circumference of 18.8 inches

The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)

Circumference of a circle = 2*pi*radius or diameter*pi

the radius is 10.5 inches. * * * * * Wrong! Circumference = 2*pi*Radius Or, Radius = Circumference/(2*pi) So circumference = 21 inches implies radius = 3.34 inches (to 3 sf)

The circumference of a circle if its radius is 3 is about 18.85

Radius = 12.414 inches (to 3 dp)

Radius of circle: 18/2pi = 2.865 inches rounded to 3 decimal places

The circumference of a circle with a 3-inch radius is about 18.85 inches. (C = r x 2 x Pi)

Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches

A circle with a radius of 3 units has a circumference of 18.85 units.

Circumference = 2*pi*18 = 113.097 inches to 3 decimal places

Radius is 18/2pi = 2.865 inches rounded to 3 decimal places

Circumference: 2*pi*3 = 6*pi inches

A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.

6 inches because the diameter is twice the radius 3+3 = 6 circumference = pi*6 = 18.849 inches

A circle with a radius of 3 units has a circumference of 18.85 units.

The circumference of a circle with a radius of 3 m is: 18.85 m.

Circumference = 2*pi*6.5 = 40.841 inches rounded to 3 decimal places

Circumference = 2*pi*3 inches Area = pi*32 square inches

circumference = 2*pi*14 = 87.965 inches rounded to 3 dp

circumference = 2*pi*6 = 37.699 inches to 3 decimal places

The radius is 3.

The circumference of a circle with a diameter of 3 inches is 9.425 inches.

Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches

radius = 48/(2*pi) = 7.639437268 or 7.639 inches to 3 decimal places
