Revered members, Please look at my attachment. I need to find the centroid of the plane area. The radius of semi circle at the bottom and top is 3 cm. I dont know how to proceed. Should i use the formula for semicircle or semi ellipse? Help in this regard will be greatly appreciated. In fact i have no clue as to how to proceed. Please help
The centroid (or center of mass) along one axis is the sum of each point mass multiplied by its distance from a reference point, then divided by the sum of each point mass. You can express this as: The first step would be to find the centroid of a semi-circle. Do you know how to calculate the area of a circle using integrals knowing the formula for circumference? circumference = If so, calculate the centroid of a semi-circle by dividing the semi-circle into small half rings going out from the center of the circle.
