Oh, dude, you're hitting me with some geometry now! So, the radius of a circle is half of its diameter, right? That means if the diameter is 50mm, the radius would be 25mm. And if you want to find the diameter from the radius, just double it! Simple math, man.
Well, honey, if the radius of a circle is 50mm, then the diameter is twice that, which is 100mm. So, there you have it, the radius is 50mm and the diameter is 100mm for each circle. Hope that clears things up for ya!
Ah, let's take a moment to appreciate these circles with a radius of 50mm and a diameter of 100mm. Just imagine the gentle curves and symmetry they bring to our canvas. Remember, every circle has a story to tell, and these circles whisper tales of harmony and balance.

What is diameter of circle if radius is 1.5?
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
How do you find circumfrence?
The process you would use to find the circumference of a circle completely depends on what information you already have about the circle. For example, you might be given the circle's area, or its radius, or its diameter, or the length of one radian of arc along the circumference, and each of those would require a different method to find the circumference. The easiest example is the one where you know the circle's diameter. In that case, simply multiply the diameter by (pi) to get the circumference. The next easiest case is the one where you have the circle's radius ... let's say the radius is 1.5 meters. Knowing that the radius is half of the diameter, you first double the radius, and find that the diameter 3.0 meters. Then you get the circumference just as you did in the first example ... multiply the diameter by (pi). With a radius of 1.5 meter, you would find that the circumference is about 9.425 meters. (rounded)
How do you find the area of a circle that has no diameter?
The circle must have a diameter, so maybe your teacher just didn't tell you the diameter. In order to figure out the question, you need to know some information about the circle. Weather it's the radius, circumference, or diameter. So here's how you find area if you only have each of the three: 1. If you just have the radius, then square the radius. This means multiply radius times radius. Or say the radius is 4. Squaring it is 4 times 4. So once you find out the answer for radius squared, multiply radius squared by pi. (Probably use 3.14 for pi) Then there's your area. 2. If you only have the circumference of a circle, then you need to find the radius. In order to do that, you need to find the diameter. To find the diameter of a circle, you take the circumference and divide it by pi. (3.14) then you have your diameter. Since the radius is half the diameter, divide the diameter by 2. Then, once you find the radius, you may look at step 1 and use those steps to find out the area. Since your question is wondering how to find the area without knowing the diameter, then you can multiply the radius by 2 to find out the diameter. Even though you don't need to know the diameter to find the area. You just do (r times r) times pi (3.14)
Do concentric circles have the same circles?
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
Estimate the area of each circle use 3 to approximate 4 feet?
You don't mention whether the 4 feet is the circumference, diameter or radius. The area of a circle is pi times the radius squared. If 4 feet is the circumference, the area is about 1.3 feet squared. If 4 feet is the diameter, the area is about 12.6 feet squared. If 4 feet is the radius, the area is about 50.3 feet squared.
Radius of each circle?
Why is this an automotive question? The radius of any circle is half of the diameter.
What is diameter of circle if radius is 1.5?
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
What is the radius of 13cm?
tell what the diameter (d) and radius(r) of each circle is by using this information
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
What are three different size circle?
Each circle with a different radius (or diameter or circumference) is a different size circle.
If a circle has a radius of 7.5 feet what is it's diameter?
The radius is half the diameter (R = D/2). The radius goes from the center of the circle to a point along the perimeter, while the diameter goes across the entire circle, connecting two points opposite each other along the perimeter. If the radius is 7.5 feet, then the diameter is 13 feet.
What are each part of a circle?
there is a center point, an arc, a radius, a diameter, a chord.
How can you find the circumference of each circle and round to the nearest unit?
You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
Why is the diameter of a circle with a radius of 1 inch?
It is because your 1 inch is one circle 1 inch one circle one of each get it.
What is the area of a circle with 4mm?
You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility leads to a different area.
What is the are of a circle with 4 mm?
You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility gives you a different area.
What is the radius and diameter of a circle?
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.
