Views of a 3D object

Nets of 3D object

Surface area of a prism

Surface area of a cylinder

The front, back and side depend on the way the shape is shaping me.

The total of all the sides of a 3D prism.

A = LxW

If even sides are even then do it 2x

f/b = 11x5 = 55x2 = 110

t/b = 6x5 = 30x2 = 60

sides = 11x6 = 66x2 = 132

110 + 60 + 132 = 302cm

Area: A = π x r 2

Cercle + Rec: (2 x π x r2) + (2 x π x r x h)

Circumference: C = 2 x π x r

A = π x r2 ~ C = 2 x π x r

A = π x 102 = 314

C = 2 x π x 10 = 62.8

(2 x π r2)+(2 x π x r x h)

2 cercles + rectangle

2 x π 5 2 + 2 x π x 10 x 12
