RS = 6
TR = 4.5
Find TS.
R--------------T----------------S
TS = RS - TR
TS = 6 - 4.5
TS = 1.5
Did you follow?
128pi in^3
because:
Volume = Area of the base * height
Volume= pi*r^2*height
= pi4^2 * 8
= 128pi
D) 4s-10 would be the correct expression. To get the perimeter of the rectangle you would get the expresssion: (s-6)+(s-6)+(s+1)+(s+1), simplified this is equal to 4s-10.
