geometry help-diameter of a circle?

Question

if the radius of a circle is 6 square roots of 2, what is the diameter?

P.S~ i don't have money for a tutor and anyone that can help me. is there any website thats really good at explaining geometry?

Answer 1

Diameter of a circle is the distance across the circle, through the center. The radius is the distance from the center to any single spot on the outside of the circle. So, the radius is one-half of the diameter.

Answer 2

ok properly if i'm perfect you mean the circumference is 34 ft and not inches. The equation for circumference is 2pi(r) meaning you multiply 2 by capacity of pi and then the radius. undergo in concepts that the radius is 0.5 of the diameter of any circle. Multiply 34 by capacity of 12 to transform it to inches (408 in). Now set the equation 2pi(r) equivalent to 408. consequently 408 = 2pi(r) 204 = pi (r) r = sixty 4.935

Answer 3

diameter is double the radius so it would be twelve square roots of two

Answer 4

diameter is double the radius, so its 12root2
