The radius is half of the diameter, so 9 divided by 2 = 4.5 So, 4 and a half yards.
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
9
The answer is 9
The circumference is about 56.55 yards.
Diameter = 2*9 = 18 units
9 mm
