Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
The smallest perimeter for any area is achieved with a circle. The area formula for a circle is A = pi * radius squared. Where pi is a constant equal to about 3.14. In this case, 60 = pi * radius squared, then radius = square root (60 / pi) A circle's perimeter is called the circumference: C = 2 * r * pi So, C = 2 * square root (60 / pi) * pi It is approximately 27.5 meters
No. Radius is half of the diameter.
(radius+radius) times pi
This is an interesting question: very simple but incredibly difficult. I have not found a proper answer but have got a partial answer to a related question: given a number of unit squares, what is the smallest circle that they will fit into. The two are linked very simply: if 2 unit squares will fit in a circle of radius 1.118 then a unit circle can hold 2 squares of a maximum side of 1/1.118 units.The answers given below can be proved only for n = 1 and 2.1 square : radius = sqrt(2)/2 = 0.707 approx.2 squares : radius = sqrt(5)/2 = 1.118 approx.3 squares : radius = 1.2884 squares : radius = 1.4145 squares : radius = 1.58110 squares : radius = 2.12120 squares : radius = 2.89330 squares : radius = 3.485.For all integers up to 35 see www2.stetson.edu/~efriedma/squincir/
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
Helium has the smallest covalent radius
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
Lithium has the smallest atomic radius among the elements listed.
It is called the radius
Beryllium has the smallest atomic radius among the alkali earth metals.
The Hydrogen Ion has the smallest ionic radius.
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
N (smallest radius) P As Sb (largest radius)
Fluorine has the smallest atomic radius, while Francium has the largest atomic radius.
