Answer:

38.28 cm = D. 38

Step-by-step explanation:

Area of the Rectangle: l x w

Length: 6 cm

With: 4 cm

Area = 4 x 6

Area of Rectangle: 24 cm

Area of the Triangle: lw(1/2)

Length: 4 cm

Width: 4 cm

Area: 4 x 4 = 16 x 1/2 = 8

Area of Triangle: 8 cm

Area of the Circle: pi x r^2 x 1/2

Radius: 2 cm

Pi: 3.14

Area: 3.14 x 2^2

Area: 3.14 x 4 = 12.56

Area of Circle: 12.56 x 1/2

Lastly, you add them all together:

24 + 8 + 6.28 = 38.28 cm

The ratio of the heights of two similar cylinders is 1:3. If the volume of the smaller cylinder is 67cm cubed, find the volume o
irina1246 [14]

Answer:

volume = 1809 cm³

Step-by-step explanation:

The ratio of the height of two similar cylinder is 1:3 . The volume of the smaller cylinder is 67 cm³. The volume of the larger cylinder can be computed below:

If 2 object are similar and the ratio of the corresponding sides is x ,then the ratio of their volume is x³.

ratio of height = 1/3

ratio of volume = (1/3)³ = 1/27

volume of smaller cylinder/volume of larger cylinder = 1/27 = 67/x

where

x = volume of the larger cylinder

x = 27 × 67

x = 1809  cm³

volume = 1809 cm³
