Acube as a volume of 1/512 cubic meter. what is the length of each side of the cube? explain your thinking

Area of new circle with diameter GX is   π x (GX/2)^2

Step-by-step explanation:

Here G, H, and X are on the same line.  

G is the center of small circle and X is the center of large circle

Let GX be the diameter of new circle, then

Radius = GX/2

Area of a circle of radius r is given by  

A = πr^2

Here the radius of circle with diameter GX is,  r = GX/2

Therefore area of new circle with diameter GX is  A = π x (GX/2)^2
