Answer:
Efficiency (Work done per day) for :
( ˘ ³˘)/
A & B together = 1/35th
A alone = 1/60th
Thus, efficiency of B alone = Total - A’s efficiency
Step-by-step explanation:
OR Efficiency of B alone = (1/35) - (1/60) = 6/210 - 3.5/210 = 2.5/210 = 1/84th
Hence, since B completes 1/84th work daily, he would take 84 days to complete the work alone.
The distance between the center and any point on the circle is the radius. That's likely what your book or teacher is asking for.
Note: double the radius and you get the diameter
