A right circular cone having radius 5 cm and height 12 cm is given. The curved surface area of the cone is kki
Answers
Explanation:
As we know the, the total surface area of cuboid (TSA)=
\sf{ = 2(length \times breadth + breadth \times height + heigh \times length}=2(length×breadth+breadth×height+heigh×length
Now, putting the values, we get,
\sf{\implies \: TSA = 2(20 \times 15 + 15 \times 18 + 18 \times 20}⟹TSA=2(20×15+15×18+18×20
\sf{\implies TSA = 2(300 + 270 + 360}⟹TSA=2(300+270+360
\sf{\implies TSA = 2 \times 930}⟹TSA=2×930
\sf{\implies TSA = 1860}⟹TSA=1860
Now,
The lateral surface area of the cuboid (LSA)=
\sf{\implies 2 \times height( length+breadth)}⟹2×height(length+breadth)
Now, putting the values, we get,
\sf{\implies LSA = \: 2 \times 18(20 + 15)}⟹LSA=2×18(20+15)
\sf{\implies LSA = 2 \times 18 \times 35 }⟹LSA=2×18×35
\sf{\implies LSA = 1260}⟹LSA=1260
Hence, the total surface area and the lateral surface area of the cuboid are 1860cm² and 1260cm².
What answer are you looking for? The surface area? The volume? What flavor ice cream is it holding? How much is it? Where can you buy one?
The volume of a cone is Pi*r^2*(h/3) = 235.619 cu cm
The surface area of the cone is Pi *r*(r + (sqrt(h^2 + r^2))) = 240.263 sq cm
And no, I don’t know where to buy one that big!
