PRACTICE EXERCISE 3.1 Refer to Figure 3.8; disregard the differential lengths and imagine that the object is part of a spherical shell. It may be described as 3 ≤ r ≤ 5, 60° 0 ≤ 90°, 45° ≤ ≤ 60° where surface r r= 60° is AEFB, and surface is ABCD. Calculate 3 is the same as AEHD, surface 0 = = 45° (a) The arc length DH (d) The surface area ABDC (e) The volume of the object (b) The arc length FG (c) The surface area AEHD Answer: (a) 0.7854, (b) 2.618, (c) 1.179, (d) 4.189, (e) 4.276.
