How do you work out the area if given the circumference?
Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
How is a circle different from a other shape?
A circle is different from another shape because of the following reasons:- It is a perfectly rounded shape It has a circumference It has a diameter It has a radius It has chords It has sectors It has segments It has infinite lines of symmetry Its circumference divided by its diameter is the value of pi Its area is: pi times radius squared Its circumference is: 2*pi*radius or diameter*pi
A soup can is in a shape of a cylinder The can has a volume of 342cm3 and a diameter of 6cm What is the height of the can in terms of Pi?
The height of the can in terms of Pi is: about 3.85picm
What is the formula for area using pi?
It depends on the shape you need the area of, the most common one is for a circle. That is Area=Diameter x Pi
What is a complex shape with an area of 100cm and a perimeter of 30cm?
There is no such shape. Firstly, because no shape can jave an area of 100 cm. Suppose, though, that its area were 100 SQUARE cms, even then, there is no possible solution. Of all the shapes possible with a given perimeter, a circle has the greatest area. A perimeter of 30 cm means a radius of 30/(2*pi) = 15/pi cm. A circle with this radius would have an area of pi*(15/pi)2 = 225/pi = 71.62 sq cm : well below the area required.
