ngongo tapawha koki koihe ngongo tapawha motuhake me te koki koi, e whakamahia ana hei tapahi, hei whakakorikori ranei i nga mea whakarewa. I te nuinga o te waa ka wehewehea ki te diameter nui me te diameter iti.He paipa tapawha kokonga koi nui: i te nuinga o te waa he nui ake te karaehe, ka taea te whakauru atu i nga rawa me te tino whai hua mo te huri i nga mea nunui. He iti noangongo tapawha kokonga koi: i te nuinga o te wa he iti ake te karaehe, he iti ake nga rauemi, he mea tino pai mo te whakakoi i nga mea iti.
Ko te tikanga, ka nui ake te diameter o tekoki koi ngongo tapawhā, ka nui ake te pehanga ka taea e ia te tu. Na reira, i te wa e whiriwhiri ana i tekoi koi ngongo tapawhā tapawhā, Me tīpakohia kia rite ki te pehanga o te tono. I tua atu, ko te diameter o tepaipa tapawhā kokonga koika pa ano tona oranga ratonga.
I te wa e whakamahia ana enei mema maitai mo nga tuanui tira o roto, ka taea te karo i te tukanga o te ahi me te whakakikorua i te waikura, e kore e taea te whakaiti i te nui o te mahi me te utu kaupapa, engari ka hoatu ano he taakaro ki te ahua o te ahua ataahua o nga putorino maitai tapawha me te tapawha.
