A cone has a radius of 10 cm and and height of 9 cm. What is the approximate volume of the cone? Use 3.14 for π.
astraxan [27]

Answer:

The volume of the cone is 942cm^3

Step-by-step explanation:

The given cone has a radius of 10 cm and and height of 9 cm.

The volume of a cone is given by:

V=\frac{\pi r^2h}{3}

We substitute r=10 and h=9 ,  \pi=3.14 to obtain:

V=\frac{3.14*10^2*9}{3}

Simplify exponents to get:

V=\frac{3.14*100*9}{3}

Simplify:

V=314*3\\V=942cm^3

Therefore the volume of the cone is 942cm^3
