1. find the area of the composite figure.

40 units2

38.5 units2

39.75 units2

44 units2

#2: the cylinder below needs to be spray-painted. find the surface area and use π = 3.14. round to nearest hundredth.

282.62 cm2

207.24 cm2

226.08 cm2

304.25 cm2

#3:
what is the volume of a sphere with a surface area of 196 π ft2 ?

1372/ 3 π ft3

457/ 3 π ft3

226/ 3 π ft3

420 π ft3

1: Refer to the attached image. We can split the composite figure in easy figures: triangles ABC and CDE have a base AC=4 and height of 3. Their area is thus

Rectangle AEFH has sides AE=8 and AH=3. So, it has area

Finally, triangle FGH has a base HG=2 and height HF=8. So, its area is

So, the total area is

2:

The base radius is 3, so the base area is

The lateral area is the product between the height and the base circumference:

So, the total area is twice the base area plus the lateral area:

3:

The surface area of a sphere is

Solving for r, we have

The volume of a sphere is
