Are we doing all of your homework for you? Did your teacher not give you the formulas for these problems? Are you just too lazy to plug the numbers in and use you calculator?

The radius is 4 inches. The diameter is the distance from one side of the circle to the other that also goes through the center. The radius is half of the diameter. Math Extras: The circumference of a circle is the "perimeter" (distance all of the way around) and can be found by diameter times pi. The area of a circle is the total space within the circle and is found by the radius squared (radius times radius) times pi.

4 inches. Radius=diameter x 2.

2 x Radius = Diameter
So if the Diameter is 8",
2 x Radius = 8"
Therefore Radius = 8"/2 = 4"

What is 8 divide by 2? 4! Radius is equal to half of the diameter.

radius is half of diameter so 8/2 =4

Radius = diameter / 2 or
r = d/2
So
r = 8 inches / 2
r = 4 inches

4 inches (8/2, cause the radius is half the diameter)...Diameter is the distance from the endpoints going through the center while radius is the distance from the center to the circle endpoints

Radius equals diameter divided by two
R = D/2 = 8inches/2 = 4 inches

4. diameter is 2 radii. Radius is half the diameter.
Extra's:
area is radius^2 times pi.
circumfrance is pi times the diameter.
pi is the weird symbol on your calculator. Off the top of my head its 3.1415926535897932384626
