How do you find the circumference of a basketball?
The circumference is pi times the diameter. The area is pi times the radius squared.
What is the circumference with a radius of 12?
1 Expert Answer The formula for the circumference of a circle is C = 2πr, so the circumference of this circle can be represented by C = 2π(12). This simplifies to C = 24π. If we use 3.14 for π, then C = 24(3.14) = 75.36 inches.
How do we calculate circumference?
The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.
What is the diameter of a 12 foot circumference?
Setting Up the Formula or “The diameter is equal to twelve divided by 3.14.” Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches.
What is the circumference of basketball ring?
The size of the basketball rim’s radius is 9 inches and the diameter is 18 inches. The circumference of the rim is 56.5 inches.
What is the circumference and weight of the basketball?

What is the area of the radius is 12?
2 Answers. The area of the circle is 452 .
Is the relationship between the diameter and the circumference proportional?
There is a proportional relationship between the diameter and circumference of any circle. The constant of proportionality is pi. The symbol for pi is . We can represent this relationship with the equation , where represents the circumference and represents the diameter.
How do I calculate diameter from circumference?
How do I find the diameter from the circumference?
- Divide the circumference by π, or 3.14 for an estimation.
- And that’s it; you have the circle’s diameter.
How do you calculate circumference of a pipe?
How to Calculate the Circumference of a Pipe
- Measure the diameter of the pipe. For example, assume the pipe has a diameter of four feet.
- Determine how accurate your measurement needs to be. If you need a general estimate, you can use 3.14 as pi.
- Multiply the diameter by pi.
What is the normal size of a basketball?
Ball Size. The size of the ball in women’s basketball ranges from 28 1/2 to 29 inches in circumference. The basketball in the men’s game is between 29 1/2 and 30 inches. Women’s hands are smaller than men’s hands on average, so it’s easier for women to handle the smaller ball.
How do you find the circumference of a ball?
Measure the circumference of the fitness ball. Fitness ball sizes are listed in diameter (the distance straight from one side of the sphere to the opposite side, passing through the center), not circumference. Divide the circumference by pi, or 3.14, to get the diameter.
What is the circumference of an official basketball?
A standard professional men’s basketball is 29.5 inches in circumference, leaving only a half-inch of free space for the ball to travel down through the hoop. A regulation women’s ball has a circumference of 28.5 inches. A men’s ball weighs 22 ounces, and a women’s ball weighs 20 ounces.
