$$\frac{320 \pi}{3}\approx 335.103$$

anonymous · Answer

see formula for volume of cone is 

V=(1/3) * pi * r2 * h 
 or  3.14159 *r2 * l * 4/3 where:pi = constant 3.14159...r = radius of baseh = vertical heightl = length of 'slant' edge of c

simply plug in values and get result...

so it will be 334.9m3....
