Need the volume!! Fast

4x 20 is 80 but if ther machine is broken then there is none you have to redo the test

Alex need : 1: using your compass, draw a circle and label the center  o.2:   using your straightedge, draw a diameter of the circle, labeling the endpoints  aand  b.3:   construct the perpendicular bisector of the diameter,  .4:   label the points where the bisector intersects the circle as  c  and  d.5:   connect points  a  to  b  to  c  to  d  to form the square.britannie need : 1: use the given center and the straightedge to construct a radius of the circle. use the compass to measure the radius.2: using this radius, place the point of the compass at the endpoint of the radius on the circle and make an arc that intersects the circle.3: keeping the same radius, place the point of the compass at the point of intersection of the arc (from step 2) and make another arc that intersects the circle.  4: continue making consecutive arcs around the circle as described in step 3 until the circle has been divided into six 60º arcs.5: construct the sides of the equilateral triangle by connecting the endpoints of three consecutive 120° arcs.
