Whats a diameter and how do u calculate it?

And whats a circumference?

thankyou!

i needed help since eqao is on Monday

The diameter is part of a circle. To get the circumference of a circle, you need to multiply the diameter by pi. (3.14)

Have a nice day!!! ( ͡° ͜ʖ ͡°)

A diameter is a straight line that passes through the center of a circle and touches two opposite points on its circumference. It is essentially the longest chord of a circle.

To calculate the diameter of a circle, you need to know either the radius or the circumference. The radius is the distance from the center of the circle to any point on its circumference. The formula to calculate the diameter is simply twice the radius (d = 2r). So, if you know the radius, you can multiply it by 2 to find the diameter.

Now, let's talk about circumference. The circumference of a circle is the distance around its outer edge or boundary. It is the perimeter of a circle.

To calculate the circumference of a circle, you need to know the radius or the diameter. The formula for finding the circumference is π (pi) times the diameter (C = πd) or alternatively, you can also use the formula 2π times the radius (C = 2πr), where π is a mathematical constant approximately equal to 3.14159. So, if you know the diameter, you can multiply it by π to find the circumference or if you know the radius, you can multiply it by 2π to find the circumference.
