Add the following decimals. a. 12.8 + 27.38 + 0.562 b. 13.46 + 5.003 + 0.0321 c. 0.952+ 1.57 + 0.803 d. 43 + 2.386 + 3.74 e. 13.678 + 52.04 + 5.276 + 0.63 f. 0.6 + 0.54 + 1.2 + 116.086 g. 54.2 + 5.42 + 0.542 + 0.0541 h. 10.01 + 9.987 + 3.75 + 2.316

a. 12.8 + 27.38 + 0.562 = 40.742

b. 13.46 + 5.003 + 0.0321 =18.4951

c. 0.952+ 1.57 + 0.803 =3.325

d. 43 + 2.386 + 3.74 =49.126

e. 13.678 + 52.04 + 5.276 + 0.63 =71.624

f. 0.6 + 0.54 + 1.2 + 116.086 =1.7361

g. 54.2 + 5.42 + 0.542 + 0.0541 =60.2161

h. 10.01 + 9.987 + 3.75 + 2.316=26.063

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
