What is the circumfrance of a circle and how do you find it?
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
The equation of the inner circle is x2 plus y2 equals 4 the radius of the outer circle is four times the radius of the inner circle write the equation of the outer circle?
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
If the outer diameter of a metal pipe is 2.84 inches and the inner diameter is 1.94 inches the thickness of the metal is?
The answer is the difference between the radii of the inner circumscribed circle and the outer circumscribed circle. The radii equal half of the corresponding diameters; therefore, the thickness is 1/2(2.84 - 1.94) = 0.450 inches, where the last digit is depressed because it may not be accurate within + 1. (The difference between 2.84 and 1.94 has only two significant digits.)
A c program to square matrix?
A C program to square matrix is a math problem. In the math problem you write down all the outer boundary values of matrix in a circle, then write down the inner value.
What are the subsets of the universal set are represented in a Venn diagram by what shape a circle an oval or a rectangle?
The universal set is the outer rectangle and all subsets are circles or ovals. In terms of the Venn diagram, there is no difference between circles and ovals.
What is the outer edge of a circle?
It is the circle's circumference
What is the outer edge of a circle called?
circumference
Outer periphery of a circle?
the circumference
What is the edge of a circle called?
The outer edge of a circle is called the circumference.
What is there radius of a circle?
The radius of a circle is the distance from the centre of the circle to its circumference - which is the outer limit of the circle.
How is the circumference of the inner circle is 44 feet. the distance between the inner circle and the outer circle is 3 feet. by how many feet is the circumference of the outer circle greater than th?
It is greater by 18.8 feet.
Perimeter of the sector?
A track 7m wide consists of two concentric circles. The circumference of the inner circle is 440m. Find, 1) the radius of the outer circle 2) the circumference of the outer circle.
Is the circumference area?
No, it is the outer edge of the circle; the rim; the perimeter
How do you know circumference?
The circumference is the perimeter of a circle, total outer length of a circle. Use 2 x (pi) x r to calculate the circumference, where (pi)= 3.142, r= radius of circle. :)
What theorems are there for concentric circles?
*If two pair of tangent of inner circle making angles on the circumference of outer circle then the angles so formed are equal . *Any two tangent of inner circle within the outer circle's circumference are equal in length .
What is circumference of a circle in terms of pi?
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
Is the area of a circle the same as the circumference of a circle?
No. The circumference is the distance round the outer edge of the circle, calculkated as 2 x pi x the radius.The area is calculated as pi x the square of the radius.
