It is possible but it would be a waste of your time.
the diameter would be 7 inches
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
The diameter would be 16 inches because the diameter is twice the radius.
The circumference of a cirlce that has a diameter of 3 inches would be about 9.42 inches
The radius is one half the diameter so if the diameter is 8 inches then the radius is 4 inches.
If the circle is 8 inches in diameter, its circumference would be: 25.13 inches (diameter x Pi = circumference)
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
Would that be 60 inches across for a 60 inch diameter?
radius = 1/2 diameter = 4 inches
4 inches. The radius = 1/2 of the diameter
Radius = Diameter/2 so the radius of a "a" is 4 inches.
It would be 6 inches.
