 ## How do you find the 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. You can also use the circumference and radius equation.

The diameter is a more general concept than the radius. It’s defined as the maximum distance between two points. A square, for instance, has a diameter. … So its more useful to think of angles via a circle’s radius than its diameter in that sense.

## Is radius half the diameter?

The radius is half the diameter, or . The diameter of this circle is 36 feet, so the radius is feet. The radius is 18 feet. The distance around a circle is called the circumference.

## What is the opposite of radius?

## What is Radius and Diameter?

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 radius if the diameter is 16?

If the 16 cm is the diameter then the radius is 8 cm.

## How do you convert radius to diameter?

That line is the diameter. Just divide by two; half the diameter is the radius. For example, if you have a diameter of 6cm, just divide by 2. You will get half of the value, which is 3cm; this is the radius.

## What is the radius of a 6 foot circle?

If the radius of your circle is 3 feet, for example, its diameter is 3 × 2 = 6 feet; and the circumference is then 6 × 3.14 = 18.84 feet, or 6 × 3.1415 = 18.849 feet if you’re asked for a more exact answer.

## What is the formula of area?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.

## What does a radius represent?

In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

## How do you find radius when given area?

how do you find the radius of a circle if you only know the area of the circle. Do you somehow reverse the Pi formula. and hence if you know A, divide it by π and then take the square root to find r.
