<prompt> Bala sebaka se holima tanka ea cylindrical e nang le radius ea 9 cm le bolelele ba 8 cm.nan  <response>: Instruction in English: Calculate the surface area of a cylindrical tank with radius 9 cm and a height of 8 cm. . Response in English: The total surface set of a cylindrical shape can be calculated by breaking it into three parts: The top, bottom, and side. The top and bottom are both circular shapes, while the side is a rectangle shape.We can calculate the surface area of each part as follows:1. The surface area of the top circle is obtained by using the formula for the area of a circle which is πr2, where r is the radius of the circle. So, for our cylinder, the top surface area will be π 92 3.1415 81 254.34 cm2.2. The surface area of the bottom is the same as the top so it is also 254.34 cm2.3. The surface area of the side surface area of a cylinder can be represented as a rectangular plane whose dimensions are the perimeter of the circular base and the height of the cylinder. So it is equal to the product of the circumference of the base and the height of the cylinder: 2πr h.In our case, the side surface area will be equal to 2π 9 8 452.16 cm2.To obtain the total surface area of the cylinder we sum the surface areas of the top, bottom, and side surfaces: 254.34 254.34 452.16 960.84 cm2. So, the total surface of our cylindrical tank is equal to 960.84 cm2. . Response in Sesotho: Kakaretso ea holima sebopeho sa cylindrical e ka baloa ka ho e arola likarolo tse tharo: ka holimo, tlase le lehlakoreng. Bokaholimo le tlase ke libopeho tse chitja ka bobeli, ha lehlakore e le sebopeho sa khutlonnetsepa. Re ka bala sebaka se ka holimo sa karolo e ngoe le e ngoe ka tsela e latelang: 1. Sebaka se ka holimo sa selikalikoe se ka holimo se fumanoa ka ho sebelisa mokhoa oa sebaka sa selikalikoe se πr 2, moo r e leng radius ea selikalikoe. Kahoo, bakeng sa silindara ea rona, sebaka se ka holimo se tla ba π 92 3.1415 81 254.34 cm2. 2. Sebaka se ka tlase se tšoana le se ka holimo kahoo se boetse se le 254.34 cm2. 3. Sebaka se ka holima sebaka se ka thōko sa cylinder se ka emeloa e le sefofane se nang le mahlakore a mabeli seo litekanyo tsa sona e leng sekhahla sa setsi sa selikalikoe le bophahamo ba cylinder. Kahoo e lekana le sehlahisoa sa selikalikoe sa motheo le bophahamo ba silindara: 2πr h. Tabeng ea rona, sebaka se lehlakoreng se tla lekana le 2π 9 8 452.16 cm2. Ho fumana kakaretso ea sebaka sa cylinder re akaretsa libaka tse ka holimo, tse ka tlaase le tse ka thōko: 254.34 254.34 452.16 960.84 cm2. Kahoo, bokaholimo ba tanka ea rona ea cylindrical bo lekana le 960.84 cm2.
