all you have to do is take the number 10 and mulitply it by pie which is 3.14 which gives you the answer as 3.140
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
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.
Area of circle: 18pi Radius of circle: square root of 18 = 3 times square root of 2 Using Pythagoras' theorem each side of the square is 6 units in length
To find the circumference of a circle in rhombus you eat SH*t .
Half the square root of the square radius equals the circle radius.
It is: 128/4 = 32 which is a side of the square and so 32*pi is the circumference of the circle
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
A = 0.785 square units.
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
The perimeter of a circle is the circumference. If you mean the circle is drawn around (and touches the 4 corners of) a square, and you know the perimeter of the square, you divide the square's perimeter by 4, do pythagorean's theorem on the 2 sides (legs) to find the hypotenuse, and that hypotenuse will be the diameter of the circle. You then multiply that diameter you get by pi to get the circumference.
A circle with an area of 100.53 square units has a circumference of 35.542 units.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
