How to draw a shape with a perimeter that is 12 or 15 or 18 or 21 and the area is 12?
The perimeter and area of a shape do not provide sufficient information. With a given perimeter, the largest area that you can enclose is a circle, but you can then flatten the circle to reduce its area. Similarly, in terms a of quadrilaterals, a square has the largest area, but it can be flexed into a rhombus whose area can be made as small as you like. All that can be said is that there is no shape with a perimeter of 12 units whose area is 12 square units.
How do you draw the radius of a circle?
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
What is the perimeter of a circle with the radius of 12?
2*pi*12 = 75.40 units
What is the perimiter of a circle with a diameter of 12cm?
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
What name is given to the perimeter of circle?
The perimeter of a circle is its circumference
