If the radius of a circle is 8 cm, the circumference will be: 50.3 cm (C = r x 2 x Pi).
The area of a circle is pi times radius times radius. 6 cm = 2 times 3 cm radius = 3 cm. SO, pi times 3 cm times 3 cm 9 pi pi is approximately 3.141592... 9 times 3.141592... is 28.274328...
Volume = pi*102*8 = 800*pi cubic cm
just do it regularly then divide the volume by four when you get the volume answer ============================================================= The original cone is say, 3 cm high and has a radius of 8 cm. the formula is pi times the radius squared times the hight, so pi*64*3=192pi. the second formula is 3*4 squared times pi, so 48pi, which is one fourth of 192 pi.
Volume: pi*64*6 = 384*pi cubic cm
