That might be the diameter of the circle

$134,820
Step-by-step explanation:
is the correct answer
<span>The unit that would be best to use for measuring the weight of a stapler are grams. Since a stapler is not too heavy, you don't need a large unit for measurement of weight. Kilograms would be too large, because normally staplers do not weigh a couple of kilograms, but rather a certain number of grams. Hope I helped! :) Cheers!</span>
You can use the pythagorean theorem.
a^2+b^2=c^2
a=9
b=b
c=41
9^2+b^2=41^2
81+b^2=1681
b^2=1600
b=+/-40
but since this is a geometric scenario, answers will only lie in the positive real number set. That's why answer is +40 or C.
