Find the volume and surface area of the following solid: a hemisphere attached on top of a cylinder. i'm not sure if the picture resolution is clear for everyone to see and understand, so i'll describe its properties as well: hemisphere 's radius=7cm cylinder's height= 10cmcylinder 's radius= 7cmtotal height of the solid= 17cm me out with this question. i am in dire need of the answer, as my finals are nearing. if there is any confusion with the question, ask me. i'll be glad to elaborate. you.

Step-by-step explanation:

Here,

radius of hemisphere and cylinder(r)=7 cm

height of the cylinder(h)= 10 cm

Now the volume of cylinder(V1) is,

And the volume of hemisphere(V2) is,

Total volume=V1+V2=1540+718.67= 2258.67 cu.cm

Surface area of cylinder(A2)=

Surface area of hemisphere(A2)=

Then total Surface area=A1+A2

=748+308=1056 sq.cm

what are the

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
