You will need the formula for the volume of a cone.
πh
r= 6 cm
To find the height, you need to use the Pythagorean theorem.
a²+ b² = c² (a and b are the 2 legs and c is the hypotenuse)
b =
b= = 8
h= 8 cm
remember PEMDAS!
π8
π(36)8
π(12)8
V= 96π
Answering in terms of π is more accurate because it is actually infinite so when it gets rounded to 3.14, that is only an approximation of pi. (π is actually 3.1415926535897932384626433 etc.)
