Only circles (or spheres) have a diameter
Yes
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
Circles have diameters, rectangles have diagonals.

you take the diameter and divide it in half then you have the radius. Take the radius and multiply the radius by its self (radius squared) then multiply by 3.14 (pi) example: Diameter is 24 find the area. 24 divided by 2 is 12 12x12= 144 144x3.14= 452.16
Radius, Diameter, Arc,Seicircle, Circumference and area.
you find the surface area of a circle by first finding the area of the circles/ two ends. you do this by multiplying the diameter by pi then multiply by two, that is both ends put together then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder. circumference= pi times the diameter then add all your calculation together, and you have the surface area of your cylinder :)
it would be the diameter of the smaller circle times sqrt 2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Pi times the diameter of a circle gives its circumference.
Diameter is 8.64444
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
A diameter is a line. A single line cannot enclose a space, and thus has no area.
Circumference of any circle = 2*pi*radius or pi*diameter
The area of a circle with a diameter of 6 units is: 28.27 square units.
