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).
