The radii are 17 or less ( for 34pi) and 10 or more ( for 100pi)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

the mistake in the pattern is that :
b. the decimal point was moved one too many place values each time
the correct pattern could be made by :
b. moving the decimal point to the right the same numbers of place values as the exponents
