Cone

The circular cone of height 15 cm and volume 5699 cm3 is at one-third of the height (measured from the bottom) cut by a plane parallel to the base. Calculate the radius and circumference of the circular cut.

Correct answer:

r =  12.7 cm
o =  79.79 cm

Step-by-step explanation:

V=5699 cm3 h=15 cm  V = 31   π   r02   h  r0=π h3 V=3.1416 153 569919.0476 cm  r=32 r0=32 19.0476=12.7 cm
o=2π r=2 3.1416 12.6984=79.79 cm
