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
I think this means we have a shape with a perimeter 39cm and we are asked what is the smallest area. It is a rectangle of length 19.5cm and width zero. Or perhaps it should read area 49 cm squared., what is the smallest periimeter. A circle with 49=pi x r2. Then perimeter=pi x 2r
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
Never heard of centermetres before, and an area cannot be 120 centimetres because that is a measure of distance, not area. Instead, let us start with an area of 120 SQUARE centimetres. For a given area, the shape with the smallest perimeter is a circle. A circle with an area of 120 sq cm would have a radius of 6.18 cm and so a perimeter of 38.83 cm (to 2 dp).
circle: no corner triangle: 3 corners rectangle and square:4 corners pentagon:5 corners
circle has the smallest area
The smallest concentric circle used by Congress to identify their strongest supporters is referred to as:
approximately zero
yes that's true
Through the smallest circle.
There is a contradiction in the question. A circumscribed circle is the smallest circle that will contain the shape in question. For example, the circumcircle (circumscribing circle) of a triangle is the smallest one which will contain the triangle. However, the question refers to "within which the circle" which would imply an inscribed circle. This is the biggest circle that can be wholly enclosed within the shape in question. The two are obviously not the same and the question needs to be clear as to which one of the two is intended.
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
any ellipse (including any circle)
it is radius of smallest circle that can be drawn by the vehicle during turning.
None. You can rotate a circle by the smallest possible angle that you can think of and it will be an angle of symmetry. And then you can halve that angle of rotation and still have rotational symmetry. And you can halve that angle ...
If you're talking about a pie chart, each wedge in the circle is demonstrating a percentage. The largest wedge would be the largest percentage, the smallest would be the smallest percentage.
Meridians of longitude are half-circles. All of them have the same length.Circles of latitude have zero length at the poles, and are longest at the equator.
