# What is the radius of the diameter is 28?

## What is the radius of the diameter is 28?

radius is the half of diameter, so radius is 28÷ 2 =14 cm.

### What is the area of the circumference is 28?

Area of the circle = πr2 = 256π cm2 .

What is the radius of a circle diameter?

The radius of a circle is a line segment that starts from the center of a circle and ends at the circumference of the circle. It is half the length of the diameter of a circle, i.e., Radius = Diameter/2.

What is the radius of a 5 inch diameter circle?

=25π or approximately 78.54 square inches.

## What is the circumference if radius is 6?

Take π=3. 14, the circumference of a circle with radius =6 cm is 37.

### How do you find a circumference?

To find the circumference of a circle, multiply the circle’s diameter by pi (3.14).

What is the formula of diameter and radius?

The formula for the radius can be written as r=d2, and the formula for diameter can be written as d=2r.

How do you convert radius to diameter?

Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That’s it; you found the circumference of the circle.

## Is radius half of diameter?

The radius of a circle is the length of the line segment from the center of a circle to a point on the circumference of the circle and diameter is a line segment from one end of the circle to the other end of the circle passing through the center of the circle. So, the radius is half the length of the diameter.

### What is the diameter of a 6 inch circumference circle?

18.84 inches
Find the circumference. The diameter of the circle is 6 inches. We can substitute this given information into our formula and solve for the circumference of the circle. Our answer is 18.84 inches.

What is the area if the radius is 6 cm?

The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=6 into the formula for the area of a circle. Pi π is approximately equal to 3.14 .

What is the circumference with a radius of 5?

A circle with a radius of 5 units has a circumference of 31.416 units.

## How big is a circle that is 28 inches across?

How far around is a circle that is 28 inches across? The circumference of a circle is pi times its diameter. The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.

### How to calculate the size of a circle?

1 The diameter – defined above 2 The radius – the distance from the circle’s center or origin to the edge, one half the diameter 3 The circumference – the length of the outside boundaries of the circle

Is the radius of a circle the same as the diameter?

The radius is the distance between the centre and any point on the outer edge of a circle. Diameter of Circle This is the diameter of a circle that corresponds to the specified radius.

What are the three dimensions of a circle?

There are three dimensions most often used to describe a circle: 1 The diameter – defined above 2 The radius – the distance from the circle’s center or origin to the edge, one half the diameter 3 The circumference – the length of the outside boundaries of the circle More
