We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
Answer: Radius: 1) from point H to point A and 2) from point H to point G
Diameter: 1) from point E to point A and 2) from point D to point G
Step-by-step explanation:
Radius is from the exact point of the middle of the circle until the circumference.
Diameter is a straight line passing from side to side through the center of the circle.
