ACTIVITY 2. Answer the following problems completely.
1. A carpet is to be installed in a room of length 9.72 m and width 5.3 m.
Find the area of the room retaining the proper number of significant
figures.
2. The speed of light is now defined to be 2.997 924 58 x 10" m/s.
Express the speed of light to (a) three significant figures, (b) five
significant figures, and (c) seven significant figures.
3. Suppose your hair grows at the rate of 1/32 inch per day. Find the rate
at which it grows in nanometers per second. Because the distance
between atoms in a molecule is on the order of 0.1 nm, your answer
suggests how rapidly atoms are assembled in this protein synthesis.
4. The base of a pyramid covers an area of 13.0 acres (1 acre = 43 560
ft') and has a height of 481 ft. If the volume of a pyramid is given by
the expression V= bh/3, where b is the area of the base and h is the
height, find the volume of this pyramid in cubic meters.
