What equation would you use to find the volume of the following:

V=lwh-{4/3}{\pi}r^{3}

V=lwh+{4/3}{\pi}r^{3}

V=lwh-{4}{\pi}r^{2}

V=lwh+{4}{\pi}r^{2}

What equation would you use to find the surface area of following:

SA=2(lw)+2(wh)+2(lh)-2{\pi}rh

SA=2(lw)+2(wh)+2(lh)+2{\pi}r^{2}+2{\pi}rh

SA=2(lw)+2(wh)+2(lh)+2{\pi}rh

SA=lwh+2{\pi}r^{2}+2{\pi}rh

9.

What equation would you use to find the surface area of the following:

SA= 2(lw)+2(wh)+2(lh)+{1/3}{\pi}r^2

SA= 2(lw)+2(wh)+2(lh)-2{\pi}r^{2}+2{\pi}rh

SA=2(lw)+2(wh)+2(lh)-({\pi}r^{2})-2{\pi}rh

SA= 2(lw)+2(wh)+2(lh)+2{\pi}rh
