If the radius is 6 inches, you can do a couple different things. You can do 3.14 times 6 then double it. Or you can do 6.28 times 6. Either way it comes to the answer, 37.68 inches is the cicumference. You can also double the radius to make it the diameter (12) and multiply by 3.14 to get the same answer: 37.68. The formula is C=rpie2 or C=dpie. So for this problem you would do C=6 times 3.14 times 2. Then substitute in for the variables until you solve it all. Good luck!

What does the 6 ins. refer to? Diameter ,or circumferebce. ???
Please clarify.
I assume 12 is diameter. If so 12/2 is radius of 6in. 6x6xpi is 113.1squared inches
Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.
Curved surface area = pi*radius*slant length = 792 square cm radius = 792 divide by (pi*slant length)
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Well, darling, to find the radius of a circle when the area is 96, you first need to remember that the formula for the area of a circle is πr^2. So, plug in the area of 96 and solve for the radius. The radius would be 4√(π), or approximately 6.93 units. Voilà!
