A sphere, a cyclinder And a cone are of the same radius and same height.find the ratio of their curver surface areas?
Answers
Answer:
here slant height I of cone=Vh^2+r^2 =vr^2+r^2 =v2r^2 =
rv 2
CSA OF
sphere. cylinder. cone
4πr^2. 2πrh. πrl
4πr^2 2πr^2. πrxrv2
4πr^2. 2πr^2. V2xπr^2
Ratio = 4π:2π:v2π
= 4:2:v2
= 2v2: v2:1
Step-by-step explanation:
reproductionreproduction is the availability of the living organism to produce young ones similar to themselves it is one of the most important characteristic of like all living things reproduce all plants animal and other living organism exist because of reproduction in class 7 you have learnt about reproduction in plants let us now study about reproduction in animals animals reproduce is of two types a sexual reproduction and sexual reproduction asexual reproduction in the production of young ones by a single parents without the formation and fusion of gametes is called a sexual reproduction now individual so formed are a genetically identical to the parents it is a private method of reproduction that is simple than sexual reproduction sexual reproduction takes place by the following process binary fusion multi multiple fusion budding sexual reproduction production of young ones by the formation and fusion of special cells called game its contribution buted generally bye to parents male and female is termed as a sexual reproduction by unlike sexual reproduction the young ones are not genetically identical to the balance reproduction pattern differ in animal have been classified into three types of the basics of a sides of their fertilization and development Male reproductive
