how would yk that the radius is 1m?

 

[kkk579]

for this q could u also do the following:
a=v squared/r
v=2pir/t
since t has to be 60 or more let t=60
therefore r must be 893.65m or more

Yes that seems to also work. The solutions probably did their way so you don't have to do a simultaneous equation to find the radius.

Why are you being so condescending all over the forum are you trying to get banned?

if you let radius be r


r will cancel out anyway. Letting r=1 just avoids any complicated arithmetic
