Answer 1

Answer:

Step-by-step explanation:

There are two shapes in the the composite figure

So, Volume of composite figure :

Volume of ( Cuboid + Cylinder )

Volume of Cuboid (Rectangular prism) :

radius = diameter ÷ 2 = 8 ÷ 2 = 4 cm

 

Answer 2

Question :

Find the volume of composite figure :

Solution :

There are two shapes in the the composite figure

So, Volume of composite figure :

$\longmapsto$ Volume of ( Cuboid + Cylinder )

_____________________________

Volume of Cuboid (Rectangular prism) :

$\large \boxed{l \times b \times h}$

• $12 \times 8 \times 4$

• $384 \: cm {}^{3}$

_____________________________

radius = diameter ÷ 2 = 8 ÷ 2 = 4 cm

Volume of Cylinder :

$\large \boxed{\pi {r}^{2} h}$

• $3.14 \times 4 \times 4 \times 5$

• $251.2 \: \: cm {}^{3}$

_____________________________

Volume of Composite figure :

• $384 + 251.2$

• $635.2 \: cm {}^{3}$
