Answer:

SA of Cylinder = 2πr(r + h)

SA of Triangular Prism = (2 × Base Area) = (S¹ + S²+ S³)L + bh

SA of Cube = S² or S • S

SA of Cone = πrs = πr√(r² + h²)

SA of Sphere = 4*Pi*R²

Step-by-step explanation:

Hope its help to you ✨

God bless you and stay safe po :>

What is the surface are of the cylinder, triangular prism, cube, cone and sphere?

☞︎︎︎Answer☜︎︎︎

Surface area of the Cylinder

First get a Lateral area of the circumference and height of the cylinder.

L.A. = 2πrh

Then the surface area of the cylinder.

S.A. = L.A. + 2B

Surface area of the triangular prism

First get the lateral area from the product of the perimeter of the base and the height.

L.A. = ph

Then the surface area of the triangular prism.

S.A. = L.A. + 2b

Surface area of the Cube

S.A. = 6 ( side × side ) or 6 ( s² )

Surface of the cone

S.A. = πr ( r + s )

Surface area of the sphere

S.A. = 4πr²

π or pi is equivalent of 3.14

I hope that helped
