You use the information you're given, along with the facts and formulas you know about the geometry of a circle.
facts about a semi circle
== == 1) They are the only one-sided shape with an area 2)A straight line is a circle with an infinite area 3)They have no angles 4)A circle is the locus of a point equidistant from another central point 5)A circle has an infinite amount of lines of symmetry hope this helped :D
A pie chart is used to compare facts with each other visually in the form of a circle whereas pi is used for example in finding the area of a circle.
Its A Circle.
Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Using 3.14 as Pi the area of circle is: 0
the area of the circle is increased by 400%
