Answer:
V = 45 pi
V =141.3
Step-by-step explanation:
The volume of a right cone is given by
V = 1/3 pi r^2 h
We know the radius = 3 and the height is 15
V = 1/3 pi *(3)^2 *15
Let pi = 3.14
V= 45* 3.14
Either your answers forgot pi
Hence the fraction of a pie that each slice represent is: 1,8
The formula is 1/2h(a+b)
h stands for the perpendicular height
a and b stand for the two horizontal lengths which are parallel to each other
