Uhh, answer choices?
In any case, since
is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem,
Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so 
Your answer is B 100,000 × 1,000,000 = (1 × 10^5) × (1 × 10^6) = 1 × 10^(5 × 6) = 1 × 10^30 because...
100,000=1×10^5
1,000,000=1×10^6
And 5×6=30
Also its not A because 5×6=30 not 11 its not C because 5×6=30 not 13 and when it came down to rather B or D I choose Because once again 5×6=30 no 42.
Basically all of the options are worded correctly but their they didn't multiply it the same at the end which is 5×6
Your answer is B.
8/5
We have to just divide.
Here 1 is the quotient while 3 is the remainder when 8 is divided by 5.
So, 8/5 is also equal to 1 3/5.
