Mathematics N6 Volume and Volume Moments AUGUST 2023

[@Valerie-Ananaba]

Sir do we divide the radius by 2 like the centroids when calculating center of gravity?

[@mathszoneafricanmotives]

@Valerie-Ananaba yes but that also is affected by the axis of rotation

Hi Sir I only got -5 here when substituting with 0 but the one with 1 I got the same values and my answer was 19.859 u^4🤔

[@mathszoneafricanmotives]

Well done, that's the idea there, yes

[@givenlindanamkhatshwa9282]

For volume moment we use u^4 as a unit neh

[@mathszoneafricanmotives]

Yes exactly 💯
