What is the diameter of a circle with a 9 radius?
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
What is the circumference of circles?
The circumference is the length of the outside of the circle. For example, if you took a piece of string and made a circle with it, then laid the string straight, the length of the string would be the circumference. The circumference of a circle can be measured by doing two times the radius of the circle times the mathematical constant, pi.
What is length of a square that has a width of 3.75 inches?
A square has equal length and width. The length would be 3.75 inches.
What is the length and width of a rectangle if the area is 2200 square feet?
The length and width can't be determined since it is a rectangle. A length would need to be given, or it would have to be a square.
What is the area of a circle with diameter of 6x?
Using 3.14 as Pi the area of circle is: 28.259999999999998
How do you find the radius of a square?
A square does not have a radius. A square, with sides of length x units, can have an inscribed circle. Such a circle would have a radius of x/2 units. Or the square could have a circumscribing circle. This would have a radius of x/sqrt(2) units.
What is the radius of a circle that has a diameter of 16 Cm?
The diameter is the whole width of the circle across the middle. The radius is the distance from the middle to the edge, so is half the diameter. Therefore the radius would be 8 cm
Why is the circle a two dimensional figure?
A circle is two dimensional because the two dimensions are width and length. 3 dimensional would be width, length and depth but since you can just write it on paper, it has no depth.
How would you find an oval with the same area of a circle?
An oval is a general word that could have different shapes. If you squash a circle evenly, the new shape in math is called an ellipse, which has an oval shape. The formula for the area of a circle is Pi times the Radius of the circle squared. The radius is half the height of the circle and also half the width of the circle. The general formula for the area of an ellipse is Pi times half the height times half the width. So we say length A is half the height of an ellipse and length B is half the width of an ellipse. When A is equal to B you have a circle. When they are different you have an ellipse. So if you want the area of the circle to be the same as the area of the ellipse, then you have to keep the height times the width the same for the ellipse as it was for the circle. As you squash the ellipse further the width must stretch out more than the height gets pushed down. For example, a circle with radius of 1 inch would have the same area as an ellipse with height ½ inch and width 2 inches because 1 times 1 is equal to ½ times 2. Another ellipse with the same area could have height ¼ inch and width 4 inches.
The length of your garden is 11 feet by 6 feet at it maxium width you are attempting to make a half circle garden how would you figure out square footage?
Assuming your aim is the largest semicircle within the rectangular area, it would be a half circle of radius 5.5 ft. A circle's area is Pi times the radius squared, so the half circle would be 1/2 * 3.14 * 5.5 * 5.5 , which equal 47.5 square feet.
How do you find the centre of a circle given part of a radius?
You would have to know the length of the radius. The center of the circle is at one end of the radius. If you just know where some part of the radius is, and not that the part touches the circle then you cannot know where the center is without at lest a point on the circumference.
What is the area if the radius is 5 of a rectangle?
The term "radius" only applies to circles, and is half of the circle's width (or diameter). For rectangles, you have a width and a height, and the area is calculated by multiplying width by height. A square's width and height are equal, so if a square is 5" wide, then the area is 25 square inches (25in2). Circle areas are calculated by multiplying the radius by itself, and multiplying the result of that by pi (π), or about 3.14. A circle with a radius of 5" would be 3.14*5*5, or 78.5in2 (78.5398 to be more accurate).
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.
Can a bowling ball be measured with a ruler?
It would depend on what you measured, it would be challenging to measure the circumference, but the radius, length or width would be easy.
Is a diameter the length of the radius multiplied by pi?
No, the diameter of a circle is two times the length of its radius. So, to find the diameter, you would multiply the radius by 2, not π.
What is the area of the largest circle that fits inside a square with 4 sides?
The diameter length of the circle would be the same as the side length of the square. If a is the side of the square, then the radius is a/2, and the area of the circle would be (1/4)(pi)(a^2).
Why can a circle not have the same area as a square?
This depends on the circle you're talking about. A theoretical circle and square most certainly could have the same area. If the circle's radius is 1, then the square's length and width would be √π. The problem here is actually in creating such a measurement in a finite number of steps. Because pi is a transcendental number, that is not possible.
