Which surfaces are actually exposed? Solve each object before moving to the next one. The touching faces are hidden.

Step 1 · Your move

A capsule-shaped model has total length 17 cm17\text{ cm} and radius 3.5 cm3.5\text{ cm}. It is a cylinder with one hemisphere at each end. What is its total outer surface area? Use π=227\pi=\dfrac{22}{7}.

r = 3.5 cmtotal length 17 cm

Total length 17 cm · radius 3.5 cm
