簡單數學一問...40分~

1, 都有可以切出圓型既橫切面既立体
2, 都係圓柱体
3, 唔會有圓型既橫切面
**同柱体既底和面成水平既橫切面,或與前後面,又或者係左右兩側平行既橫切面(視乎件柱體點樣放,而你從邊個角度去睇),而且被切出既橫切面無論切多少個,每個既橫切面既面積都會係相同既,呢d就係所謂既均勻橫切面!!

1 球體
2 圓柱體 柱體

3 角柱

1.圓柱體,球體 ,因為都係有圓的
2.圓柱體,因為不是全部圓
3.三角柱,4角柱,角柱唔識滾

RE:仲有咩係柱體的均勻橫切面??

4角柱,5角柱,6角柱.....100角柱.......

1)圓柱體,球體
2)圓柱體,
3)三角柱,4角柱,...........都係角柱

1) They are circular cylinder or sphere, or any elliptiod, anything in wheel shape, they have a common circular cross section.
2) circular cylinder, with a circular cross section and a flat base.
3) Any things with a flat base, like pyramid, cone, half sphere, all cylinders and etc.
All cylinders are defined by uniform cross section.
