Question

Find the surface area of the solid formed by the net.

Answer 1

the surface area of the figure formed by the net is the same as the area of all the figures in the net

Answer 2

also, because this is a net and has to fit together perfectly, it forms a cylinder of radius 2 inches and height 10 inches
the formula for surface area of a cylinder is 2*pi*r*h + 2*pi*r^2

Answer 3

@Nick2019
does this answer your question?

Answer 4

can you do the problem please becuase i have like 20 i need an exaple @Peter14

Answer 5

\[2 \pi r h+2\pi r ^2\]
plug in the values
\[2 \pi \times 2 \times 10+2 \pi \times 2 \times 2\]

Answer 6

or are you asking how I know it's a cylinder?

Answer 7

wait so were do i put the 4 and 10?? can you just do the problem? @Peter14

Answer 8

4 is the diameter of the circle. The diameter is twice the radius, so the radius is 2. 10 is the height of the cylinder

Answer 9

so it would be 2Pie10*2 + 2pier2

Answer 10

where the r in the last part is also replaced by a 2

Answer 11

wait my brother just helped me thanks anyways lol
