## What is the relationship between pi and pie?

Pi is a numerical ratio relating a circle’s circumference to its diameter, and pie is a circular-shaped food.

## What is the relationship between Pi and radius?

Circumference equals pi times diameter. Because the diameter of a circle is twice its radius… we can also write this formula as circumference equals 2 times pi times radius.

## Is there a relationship between Pi and C D?

C = π* D = π D For any circle, its circumference ratio to its diameter is equal to a constant known as pi.

## What is the relationship between the radius diameter and circumference of a circle?

Radius, Diameter and Circumference The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

## What is the relation between diameter and area?

Answer. Answer: So a diameter is the same as two opposing radii. The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle.

## How do you go from diameter to radius?

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.

5 feet

## How many feet is a 4 foot circle?

What is the circumference of a circle with a diameter of 4 ft?…Circumference of a 4 Foot Diameter Circle.

12.566 feet
383.02 centimeters

## What is the radius of a 30 foot circle?

Diameter of a Circle

30′0″ 94.25 28.73
30′1″ 94.51 28.81
30′2″ 94.77 28.89
30′3″ 95.03 28.97

## How many square feet is a 40 foot circle?

How big is a 40 foot circle?…Area of a 40 Foot Circle.

1,256.6 square feet
1,167,454 square centimeters
0.011675 hectares

## What is the radius of 30 diameter?

The reason being is that radii ( 2⋅radius ) are equal to the diameter of a circle. Therefore, if the diameter is equal to 30m, then the two radii equals 30m. However, you want the radius, so half of 30m ( 302 ) is 15m.

## What is the value of a circle?

The value of Pi (π) is the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159. In a circle, if you divide the circumference (is the total distance around the circle) by the diameter, you will get exactly the same number.

## What is ΠR value?

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.1416.

## Who uses pi in their job?

1. Space Scientist. Space scientists and engineers use Pi to put spacecraft into orbit. They also use Pi in more unexpected ways such as calculating the density of an asteroid by measuring the circumference and mass.
