Question

MATH
Therefore, Curved Surface Area of a Hemisphere = 2017?
wherer is the radius of the sphere of which the hemisphere is a part.
Now taking the two faces of a hemisphere, its surface area 21r + Jr
So Total Surface Area of a Hemisphere = 3ftra
Example 7: Find the surface area of a sphere of radius 7 cm.
Solution : The surface area of a sphere of radius 7 cm would be
22
40r = 4x x7x7 cm = 616 cm?
7
22
Example 8: Find () the curved surface area and (ii) the total surface​

Answer 1

Answer:

please try to send short questions as it is the very very very difficult to read such long questions so if you also put the questions in brief then also it is ok and understandable don't put in such a manner that it is so so much brief it it should be brief but it should be brief in such a way that it should be understandable on shoe and for such type of questions if you think that these are long only then you can pick send the picture of that photo along with that as it is easy to understand from the picture then from the writings
