The circumference of a circle is 66cm find the raidus π=22/7

Answer 1

To find the radius of a circle, we can use the formula for the circumference of a circle:

C = 2 * π * r

Given that the circumference is 66 cm and π = 22/7, we can substitute these values into the formula:

66 = 2 * (22/7) * r

Now, we can solve for the radius (r):

66 = (44/7) * r

To isolate r, we'll divide both sides of the equation by (44/7):

66 / (44/7) = r

By simplifying the equation further:

66 * (7/44) = r

r = 11

Therefore, the radius of the circle is 11 cm.
