Exact area of the circle: 9*pi inches
Exact area of the circle: 9*pi inches
Area formula for circle= --,,- r 2
The formula to find the area of a circle is pi x the radius squared.
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
3019.07cm²The formula is: area = 3.14 (pi) times radius squared.
9.2 i think The formula is pi*r^2
Exact area of the circle: 9*pi inches
Exact area of the circle: 9*pi inches
the formula for the area of a circle is 3.14 x radius squared
The formula to find the area of a circle is: A = pi * r2
Area of circle = πr2 Exact area = π(14)2 = 196π cm2
The area of a circle can be found with the formula (pi)r^2
Area formula for circle= --,,- r 2
The formula for double the area of a circle
The formula to find the area of a circle is pi x the radius squared.
Area of a circle = pi*radius2
