Question

HELP MEEEE PLZ. i need to Find the surface area and volume

Answer 1

Answer:

A ≈ 494.80 $mm^{2}$

V = 827.02 $mm^{3}$

Step-by-step explanation:

height ( h ) = 13 mm

radius ( r )  = $\frac{9mm}{2}$ = 4.5 mm

Surface area  = $2\pi rh + 2\pi r$

                      = 2π(4.5)(13) + 2π(4.5)

                      ≈ 494.80 $mm^{2}$

Volume = $\pi r^{2} h$

             = $\pi (4.5)^{2} (13)$

             = 827.02 $mm^{3}$
