How do you find the area common to circles?
pi r squared Area of the circle = pi (radius)2 square units.If we are supposed to find the area between two concentric circles then, let us see the definition first.Concentric circles have a common center and different radii.Area of the large circle – Area of the small circle = Area of the region between the circles.It is called as the annulus part Source: www.icoachmath.com
Can a circle be made of straight lines?
No. A circle has no straight lines. You can approximate circles with very small straight lines (that's how a computer draws circles) but mathematically, no.
What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
Why does pi multiplied by diameter equal the circumference of a circle?
Well, I asked my math teacher and thi is what she said. Okay. A long time ago there were math mathematicians. They had circles sculpted out of rock and wood and stuff like that. So anyway, these mathematicians, or MAs would study the circles by mesuring them. The MA's would take a tape and measure all the way around a circle. They then would measure across the circle. The would do big circles and small circles. They then noticed that there was a pattern. If the mutiplied the distance across the circle times a number, they would get the circumferance. The number was, 22/7 or 3.14...and pi was born. So of course we know that the decimal isn't perfect and we won't get an exact answer when mutipling by pi. But now at least we don't have to cut a circle out of stone and use a measuring tape to determine it that way. ~Minicooper Out!
What does a 4 mm circle look?
A 4 mm circle would have a diameter of 4 millimeters, meaning the distance across the circle passing through its center would be 4 mm. This circle would be relatively small, about the size of a standard pencil eraser. In terms of area, the circle would cover approximately 12.57 square millimeters.
How to draw great circles and small circles drawn?
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
What is the Radius of a small circle?
radius of any circle = diameter/2
If a circle has a radius of 8 centimeters what is the diameter?
For all circles , however, large or small The diameter is twice the radius. Diameter(d) equals(=) radius(r) plus(+) radius(r). d = r + r d = 2r . NB The diameter is a straight line from the circumference to the centre , and then out to the opposite sided circumference. It is NOT an angled line centred on the central point.
Will a circle with a radius of 4 inches fit inside a circle with a diameter of 5 inches?
no because the radius is half the diameter so it must be multiplied by two in order to find the diameter of that circle which is 4 times 4 equals to 8 so the circle which has a diameter of 5 inches is much to small for a circle with a radius of 4 inches to fit.
What is the approximate meausre of an circle?
Circles come in different sizes. You can have them as small or as large as you want.The circumference of a circle is equal to the diameter, multiplied by pi. That's the same as 2 x radius x pi.The area of a circle is equal to pi x radius2.
How do you draw and label the diameter and radius on a circle?
The diameter is a straight line from one side of the circle to the other which passes through the centre of the circle. The radius is a straight line from the centre to the boundary of the circle. To label them, you could either write the words alongside the lines or, if the circle is too small, draw arrows from the two lines to outside the circle and write the words at the end of the arrow.
The diameter is 12 and the circumference is 37.68 for the large circle for the small circle the diameter is 6 wat is the circumference?
For the small circle of diameter 6, the circumference is 18.84.
The diameter is 12 and the circumference is 37.68 for the large circle for the small circle the diameter is 6 what is the circumference?
The circumference of the small circle would be 18.84.
How do you find a circumference?
Circumference of a circle is pi * diameter. Diameter is 2 * radius. So if you know the radius, circumference is 2 * pi * radius. Now choose an appropriate approximation for pi (3.14, or 3.1416, or even the fraction 22/7), depending on your application. This will work for ANY circle, no matter how big or small it is, as long as it's a true circle and not a different elliptical shape, e.g. an oval.
How big is a 12 mm circle?
A 12 mm circle has a diameter of 12 millimeters, which is slightly less than half an inch (approximately 0.47 inches). The radius, which is half the diameter, is 6 mm. In terms of area, the circle has an area of about 113.1 square millimeters. This size is comparable to the diameter of a large button or a small coin.
What is the diameter of a small skippy lid?
It is twice its radius
How do you put 7 small circles in 3 big ones so that each big circle as 4 small circles?
Draw three circles that touch in a shape of a circle. Draw two small circles in each big one and another in the intersection. It is supposed to be a Venn Diagram.
