Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
circumference = diameter × π = 6π yards ≈ 18.85 yards
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
radius = 18/2 = 9 cm
Circumference of a circle = 2*pi*radius or pi*diameter
False because it is the other way around in that if the diameter is 18 yards then the radius is 18/2 equals 9 yards.
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).
the diameter of a circle with the radius of 9m is 18m
A circle with a diameter of 9 yards has an area of 63.62 square yards.
If the diameter is 18 ft then the radius is 9 ft = 3 yards. Then the area is pi*r2 = 28.27 sq yards.
the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
The diameter is always double the radius so in this case, it is 18cm
The answer is 9
9
The circumference is about 56.55 yards.
Diameter = 2*9 = 18 units
9 mm
