explain how to find ans. a clock has a circumference of 166cm. what is the diameter

Use the formula I showed you for your last problem.

C = pi * d

To find the diameter of the clock, you can use the formula for calculating the circumference of a circle, which is given by:

C = 2πr

Where C is the circumference and r is the radius of the circle.

Since we are given the circumference of the clock (C = 166 cm), we can rearrange the formula to solve for the radius:

C = 2πr
166 = 2πr

Next, divide both sides of the equation by 2π to isolate the radius:

r = 166 / 2π

Now that we have the radius, we can find the diameter by multiplying the radius by 2:

d = 2r
d = 2 * (166 / 2π)

Simplifying this expression gives:

d ≈ 166 / π

So, the diameter of the clock is approximately equal to 166 divided by π (approximately 52.69 cm).
