The radius of a circular car tire is 12.5 inches. Find the the circumference. Use 3.14 for pi
The circumference of a circular car tire with a radius of 12.5 inches is 78.5 inches.
To find the circumference of a circle, you can use the formula:
Circumference = 2 * pi * radius
Given that the radius of the car tire is 12.5 inches, and we are using the approximation value of pi as 3.14, we can substitute the values into the formula:
Circumference = 2 * 3.14 * 12.5
Now, we can simplify the equation:
Circumference = 6.28 * 12.5
Circumference = 78.5
Therefore, the circumference of the car tire is 78.5 inches.
To find the circumference of a circle, we use the formula:
Circumference = 2 * pi * radius
Given that the radius of the car tire is 12.5 inches and using the approximation of pi as 3.14, we can plug in these values into the formula:
Circumference = 2 * 3.14 * 12.5
Now, we can solve this equation step-by-step:
Circumference = 2 * 3.14 * 12.5
Circumference = 6.28 * 12.5
Circumference = 78.5
Therefore, the circumference of the car tire is 78.5 inches.
