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.
