Surface Area=

π R (l + R)

Given: R=2mm
l=3mm
A=(3.14)(2)(3+2)

= 3.14 \times 2 \times 5

= 3.14 \times 10 = 31.4 m m^{2}

A = 31.4 m m^{2}

Given

R = \frac{10}{2} = 5 \in

h=3in
Surface Area

= 2 π R (R + h)

= 2 \times 3.14 \times 5 (5 + 3)

= 2 \times 3.14 \times 5 \times 8

A = 3.14 \times 80 \in^{2}

A = 251.2 \in^{2}
