The answer is about 16

Step-by-step explanation:

The approsimate volume is 16.04 rounded to nearest whole number is 16.

the correct answer is 16 cubic inches

Step-by-step explanation:

We have that

the Volume of cone=(1/3)*B*h

B=the area of the base

h= the height of the cone

D=3.5 in> r=D/2=1.75 in

h=5 in

B=pi*r²> 3.14*1.75²=9.616 in²

V=(1/3)*9.616*5=48.08 in³> 48 in³

the answer is 48 in³

B. 314 cm³

Step-by-step explanation:

We are given that,

Height of the cone = 12 cm

Radius of the cone = 5 cm

Since, we need to fill the cone with the cement. So, we will find the volume of the cone.

So, Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

i.e. Volume of the cone = [tex]\frac{1}{3}\pi 5^{2}\times 12[/tex]

i.e. Volume of the cone = [tex]\frac{1}{3}\times 3.14 \times 25\times 12[/tex]

i.e. Volume of the cone = [tex]\frac{942}{3}[/tex]

i.e. Volume of the cone = 314 cm³

Hence, the amount of cement they can put in each cone is 314 cm³.

94.2
