The radius would be 4 inches !
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
Well, if you know the diameter of the circle already, then you can divide it by half to get the radius. If you don't have the diameter however, then you simply have to find the middle of the circle and measure from the middle of the circle to the edge. That would be your radius.
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
If the circle is 8 inches in diameter, its circumference would be: 25.13 inches (diameter x Pi = circumference)
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
It would be 6 inches.
The circumference of a cirlce that has a diameter of 3 inches would be about 9.42 inches
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
Two inches.
four inches
In a circle with a diameter of 4, there would be approximately 12.56 square inches in the circle.
