You can see a grey circle with a little white cirle in it with a radius of 3 What is the radius of the diagram's larger circle if the area of the shaded region is 72 pie?
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
What is the smallest perimeter area 49cm?
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
What is the smallest perimeter for a shape with the area of sixty Meters squared?
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
What is the smallest possible perimeter for a shape that has an area of 120 centermetres?
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).
What shape have the smallest number of corners of all of the shapes CircleTriangleRectangle Square Pentagon?
circle: no corner triangle: 3 corners rectangle and square:4 corners pentagon:5 corners
