The prism of the surface area is 11200
The base is the greatest surface area
= cos( -x ) * [ - sin( - x ) ] = cosx * sinx ;
cosx * sin x is the right answer !
It’s the second one, 65.4
V=1
6πd3=1
6·π·53≈ 65.44985in³
Well round to the nearest cent means to the nearest .01
So if the number is ex .0328
You round to .03
And if the number is ex .06831
You round to .07
Meaning if the number after .01 or .0_ is greater than 5 than you round up and if it's 4 or lower than you keep the number there
Sorry can't do much if this is an actual problem because you only said round to the nearest cent.
