What is the difference between radius & diameter?
Jayden JacksonDiameter is the longest line that you can draw in a circle passing through the centre of the circle.
Radius is the line joining the centre of the circle to any point on the circumference.
Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter.
Actually pi is defined to be the ratio of the circumference of the circle to the diameter of the circle. Therefore, you can solve for the diameter from that equation.

Evelyn ArboledaThe radius of a circle is the distance from the center of the circle to any point on its circumference. The diameter of a circle is the distance across the circle through its center, connecting two points on the circle's circumference. In other words, the diameter is twice the length of the radius.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Two corners of a triangle have angles of #(3 pi ) / 8 # and # pi / 6 #. If one side of the triangle has a length of #1 #, what is the longest possible perimeter of the triangle?
- The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle?
- Cups A and B are cone shaped and have heights of #35 cm# and #29 cm# and openings with radii of #12 cm# and #16 cm#, respectively. If cup B is full and its contents are poured into cup A, will cup A overflow? If not how high will cup A be filled?
