Rt. Circular Cylinder:

As = (3.14r^2)2 ) + 6.28rh,

As = (3.14 * 3^2)2 + 6.28 * 3 * 12

As = 56.52 + 226.08 = 282.6cm^2.

Rt. Rectangular Prism:

As = (8 * 5)2 + (5 * 6)2 + (6 * 8)2,

As = 80 + 60 + 96 = 236cm^2.

**Henry**, Sunday, January 9, 2011 at 11:08pmSphere: As = 4*3.14*r^2 = 4*3.14*2^2 =

50.3cm^2.

Rt. Circular cone:

As = 3.14r^2 + 3.14rs. s = sqrt(r^2 + h^2).

s = sqrt(64 + 36) = 10cm.

As = 3.14 * 4^2 + 3.14 * 4*10,

As = 50.27 + 125.66 = 175.9cm^2.
