11.6, if you need a decimal. it's in between 11 and 12
The radius of a circle is half the length of the diameter so
radius=1.5m
4 sqrt (32) + 6 sqrt (50)
4 sqrt (16*2) + 6 sqrt (2*25)
4 sqrt (16)*sqrt(2) + 6 sqrt (2)*sqrt(25)
4 *4*sqrt(2)+6sqrt(2)*5
16sqrt(2)+30sqrt(2)
46sqrt(2)
Step-by-step explanation:
I don't know how to do any of these if you could give me another question that's possibly easier
