1/5 and 1/10
1/5 cannot be broken down anymore.
Therefore, what is equal to or less than 1/10 that 1/5 can reach? 1/10.
1/10 is the least common denominator.
Based off the measures of the arcs DC and AB, your answer should be B. 36 Hope it helps.
Answer: 80 square units
Step-by-step explanation:

In mathematics, the functions of the whole part are functions that take a real number and return a whole number, either by excess or by default.
Function floor (or ground), that to each real number assigns the nearest whole number by defect, that is to say, the greater whole number equal or smaller than that real number.
Let's evaluate the extremes of the interval
x = -3
g (-3) = floor (-3) -2 = -5
x = 3
g (3) = floor (3) -2 = 1
Therefore, the graph that best corresponds to the function in the given interval is the attached graph.
