diameter is longer. radius is half of diameter
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What is the diameter of a 12cm circle?
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
What is the diameter of a circle if the radius is 27 cm?
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
If the radius of a circle is 8 feet what is the diameter?
Diameter is 16. The radius is half its diameter
What is Pi and who invented or discovered Pi?
Pi is the relationship between the diameter and the circumference of a circle.
Who first discovered the mathematical relationship between circumference and diameter that you know as pi?
The Egyptians
When was pi invented or discovered?
Pi is the value of a circle's circumference divided by its diameter and its true value has never been discovered because it is an irrational number
If a uxo measuring 24 inches in diameter is discovered how far should personnel evacuate?

When was pi discovered by the Greeks?
It wasn't because even today no one has ever discovered the exact value of pi and all we know is that its value is that of a circle's circumference divided by its diameter which is an irrational number.

When was pi invened and by who?
Pi was not invented but it was discovered by ancient mathematicians that the circumference of any circle when divided by its diameter is always equal to pi.
Who discovered pi and when?
Pi wasn't invented so much as discovered. Pi is the ratio of a circle's circumference divided by the diameter. One could say that no one invented it, but that it was discovered. The Egyptians and the Greeks had an a approximation that we are still refining to this day. It is a transcendental (non-rational) number.

The circumference of a circle divided by its diameter is equal to pi and it's unique because there is no other number that has been discovered that is equivalent to its value.
Where and when was pi invented?
It was not invented but discovered by ancient mathematicians who found that the circumference of any circle when divided by its diameter is always the same ratio for any circle.
