Find the volume of the cone​
irina1246 [14]

Answer:

The volume of the cone is 12936 cubic mm.

Step-by-step explanation:

Given

Circumference of base = 132 mm

Height of the cone = 28 mm

Solution

Formula  of circumference = 2\pi r = 132 mm

\therefore\ r= \frac{132}{2 \pi } = 21 mm

Now volume of cone = \frac{1}{3} \times\pi \times r^{2} \times h

on substituting the value of r and h  we get ;

\frac{1}{3}\times\frac{22}{7} \times21\times21\times28= 12936\ mm

thus volume of cone is 12936  cubic mm.
