How do you find the radius of a circle when given only the area?
Area = pi*radius2 So, radius = sqrt(area/pi)
How can I find circumference when only area is given?
Radius = square root of (area/pi) Circumference = 2*pi*radius
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
How do you find the area of a sector with only radius given?
To find the area of a sector when only the radius is given, you'll need to know the angle of the sector in either degrees or radians. The formula for the area of a sector is ( A = \frac{1}{2} r^2 \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. If the angle is not provided, the area cannot be determined solely with the radius.
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
How do you find the radius of a circle when given only the area?
Area = pi*radius2 So, radius = sqrt(area/pi)
How do you find the radius of a circle when your given the area?
a=area p=pi r=radius sqr(a/p)=r
How can I find circumference when only area is given?
Radius = square root of (area/pi) Circumference = 2*pi*radius
How can you calculate the radius with the area given to you?
Area of a circle = pi x radius squared, so to get the radius, divide the Area by pi (3.14159), and then find the square root of that
How do you find the area of a circle with a given radius diameter and circumference?
Given the radius, r, the area is pi*r^2.If given the diameter d, the radius is d/r so the area is 0.25*pi*d^2If given the circumference, c, the radius is c/(2*pi), so area = 0.25*(c^2)/pi
How do you find the radius if given the area is 314cm2?
Divide 314 by pi and square root the answer which will give you the radius.
What is the formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
How do you find the radius of an inscribed circle of a square given the area of the circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
How do you find a area a circle?
The answer depends on what information you are given.
What is the formula to find a area of a circle when given radius?
A = pi x radius2
How do you find the area of a circle when the radius is unknown?
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
