If a circle is 18 inches in diameter what is the circumference?
The circumference is Pi multiplied by the diameter. In this case, the circumference is 18Pi. We can only approximate this since Pi is an irrational number. The circumference is about 56.55 inches.
Does the relationship between the circumference and the diameter change when you use a different unit?
No. The units don't matter, the circumference always equals pi times the diameter. (This is only true of the circumference and diameter are in the same units. If for example, the circumference was in feet and the diameter in inches, the feet must be change to inches or the inches to feet in order for this relationship to be true.)
Explain why a cone-shaped object will not roll in a straight line?
A cone-shaped object will not roll in a straight line because the circumference of the cone changes from one end to the other. For example, if one end of the cone has a circumference of 10 inches, that end will travel 10 inches per revolution, but if the other end of the cone has a 2 inch circumference, it will only travel 2 inches per revolution.
What is the circumference of 40 inches?
Well this depends on If the radius is 40 inches or If 40 inches is the entire diameter. Circumference is determined using the formula Pi x Radius² Assuming 40 is only a radius it would be 3.14 x 40² or 3.14 x 1600 = 5024 inches If 40 inches is the entire diameter then its simply Pi x Diameter since the entire diameter is the radius squared. 3.14 x 40 = 125.6 inches.
Calculating square inches of a circle?
The area of a circle is easily found by multiplying its radius squared times the constant pi. If only the circumference is known, the radius is found by taking 1/2 of the circumference divided by pi.

Han is buying new tires for his bike. He wants to make sure the new tires will fit on his bike but the only measurement he has is the diameter of 4.0 inches. What is the circumference of the new tires in inches?
To find the circumference of the tires, you can use the formula: Circumference = π * Diameter. Given that the diameter is 4.0 inches, you can plug it into the formula to find the circumference. Circumference = π * 4.0 inches = 12.56 inches (approximately)

If for example, the circumference was in feet and the diameter in inches, the feet must be change to inches or the inches to feet in order for this relationship to be true.)
What is the radius if the circumference is 48 inches?
Well, isn't that a happy little question! To find the radius when you know the circumference, you can use the formula: circumference = 2 * π * radius. So, if the circumference is 48 inches, you can divide that by 2π to find the radius. Just remember, there are no mistakes, only happy accidents in math and in art!
What is the circumference of a hockey puck?
The circumference of a hockey puck is approximately 9.5 inches.
Are a cuttlefishes arms twice the size of its body?
no..only a few inches long no..only a few inches long
What is the circumference of W 30in x L 32 in?
A circumference is only applicable to circles but if you mean the perimeter of a 30 in by 32 in rectangle then it is 30+32+30+32 = 124 inches

How do you determine the cubic inches of a ball if all you know is the circumference?
To determine the cubic inches of a ball when you only know the circumference, you first need to find the radius by dividing the circumference by 2π. Then, you can use the formula for the volume of a sphere, V = 4/3 πr³, where r is the radius that you calculated.
What is the circumference of 40 inches?
Well this depends on If the radius is 40 inches or If 40 inches is the entire diameter. Circumference is determined using the formula Pi x Radius² Assuming 40 is only a radius it would be 3.14 x 40² or 3.14 x 1600 = 5024 inches If 40 inches is the entire diameter then its simply Pi x Diameter since the entire diameter is the radius squared. 3.14 x 40 = 125.6 inches.

Is the rectum short or long?
