Question 28:
[tex]S-2\pi r^2=2\pi rh[/tex] Subtract [tex]2\pi r^2[/tex] on both sides
[tex]\frac{S-2\pi r^2}{2\pi r} =h[/tex] Divide [tex]2\pi r[/tex] on both sides
*(Answer)*= [tex]\frac{S-2\pi r^2}{2\pi r} =h[/tex]
Question 30:
[tex]a*t=v_{1}+v_{0}[/tex] Multiply [tex]t[/tex] on both sides
[tex]a*t+v_{0} =v_{1}[/tex] Subtract [tex]v_{0}[/tex] on both sides
*(Answer)*= [tex]a*t+v_{0} =v_{1}[/tex]
