the formula is C= 2(3.14)r (the C stands for circumference and the r stands for radius) so you multiply 3.14 (pi) by the radius, then multiply that number by 2. if your radius was 12 inches, you'd multiply 3.14 x 12 = 37.68 then you'd multiply that by 2, giving you C= 75.36 inches
The circumferance is found by using the formula 2(r)(pi). r stands for the radius. The diameter, which is already given in the problem, is two time radius. Therefore the only thing you really have to do is multiple the diameter= 3 inches by pi. Circumferance is 9.425 inches.
The raduis.It's pi, r squared. the r stands for radius!

Well, darling, if the circumference is 12 inches, we can use the formula Circumference = 2 * π * radius. So, 12 = 2 * π * radius. Solve for radius, and you'll get radius = 12 / (2 * π) ≈ 1.91 inches. So, there you have it, sugar, the radius is approximately 1.91 inches.

I cannot imagine you could. both the radius and the height are considered in it's volume formula. this stands to reason as two cones of different radii can have the same volume, by the larger radius one having a smaller height and vice versa

62.8 inches. the formula for a circle's area is a = pi x r squared. substitute 3.14 for pi and 314 for a. 314 = 3.14 x r squared (divide both sides by 3.14) v 100 = r squared (find the square root of both sides) v r = positive or negative 10 . since it stands for the radius of a circle, it has to be positive. now that you know the circle's radius, you can solve the circumference formula, c = 2 x pi x r. c = 2 x 3.14 x 10 c = 62.8
The diameter of the rim is 45 cm so the radius stands at 22.5 cm.
