In the circus a monkey rides a unicycle the trainer measured the wheel and calculated that it has a circumference of 94.2 centimeters what’s the wheels radius
To find the radius of the wheel, we can use the formula:
Circumference = 2πr
Where C is the circumference, π is pi (approximately 3.14), and r is the radius.
Substituting the given values, we get:
94.2 = 2πr
Dividing both sides by 2π, we get:
r = 94.2 / (2π)
r ≈ 15
Therefore, the wheel's radius is approximately 15 centimeters.
To find the radius of a circle given its circumference, you can use the formula:
Circumference = 2 * π * radius
Here, the circumference is given as 94.2 centimeters. Rearranging the formula to solve for the radius:
Radius = Circumference / (2 * π)
Plugging in the given circumference:
Radius = 94.2 cm / (2 * 3.14)
Simplifying the equation:
Radius = 94.2 cm / 6.28
Calculating the radius:
Radius ≈ 15 cm
Therefore, the wheel's radius is approximately 15 centimeters.
