Area of circle = pie x (r squared) = πr^2
r = radius
π = pie = 22/7 or 3.142
That is the formula for calculating the area of a circle with a 10 unit radius. The answer is 314 sq units.
The formula for double the area of a circle
The formula for calculating the volume of a hexagonal prism is to take the area of the hexagon, then multiply it by the height of the prism.
The answer will depend on what information you have.
Its Area = pi * (radius ^2 - height^2)
Area of any circle = (pi) x (Radius)2
Area of a circle measured in square units = pi*radius2
The formula for calculating the area of a circle - is Pi x r x r... where r is the radius.
That is the formula for calculating the area of a circle with a 10 unit radius. The answer is 314 sq units.

The formula for calculating the area of a circle is:r²πSo, the area of a circle with a diameter of 6 inches (with a radius of 3 inches) is:3²π = 9π ≈ 28.2743 in²
Ï€*r2, where r is the radius of the circle.
Take the diameter of the circle times 3.14159 (which is PI).
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
