Area of a circle
pi radius squared. (radius squared, then multiply by pi.)
It is its square area which is found by pi*radius squared
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
Area of a circle
Pi has many usages in mathematics some of which are:- Area of a circle = pi*radius squared Circumference of a circle = diameter*pi or 2*pi*radius Surface area of a sphere = 4*pi*radius squared Volume of a sphere = 4/3*pi*radius cubed Volume of a cone = 1/3*pi*radius squared*height The value of pi is found by dividing the circumference of a circle by its diameter
pi radius squared. (radius squared, then multiply by pi.)
It is its square area which is found by pi*radius squared
It is its square area which is found by pi*radius squared
It is its square area which is found by pi*radius squared
the area of a circle is found by the formula (pi)r^2 ...pi times the radius squared... so in this case, 36pi
pi times the radius squared pi r squared
circumference of a circle = 2*pi*radius area of a circle = pi*radius squared
pi x radius squared
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
