radius = 18/2 = 9 cm
Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
The radius is half of the diameter, so 9 divided by 2 = 4.5 So, 4 and a half yards.
Circumference of a circle = 2*pi*radius or pi*diameter
radius = 18/2 = 9 cm
Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
r= 9 so diameter is 2x the radius =18 cm
The diameter is always double the radius so in this case, it is 18cm
A circle with a radius of 4.5 cm has a circumference of 28.27 cm
A circle with a radius of 9 cm has an area of 254.47 square cm
18mm or 1.8 cm
Doubling the radius doubles the circumference.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
9 cm (r = d/2)
r= 9 so diameter is 2x the radius =18 cm
the diameter of a circle with the radius of 9m is 18m
