maybe you could help me with this one too @saiberz

anonymous · Answer

If it hangs over an inch all around it means the radius of tablecloth is one inch higher than table radius 

Dt= 2Rt = 40 
Rt = 20

Rtc=20+1 = 21
A=pi*r^2
Atc=pi*21^2=1385.44

anonymous · Answer

it is almost the same as 1384.74 ,the difference is beacuse how many digits of the number pi you use
