Answer:
Using 3.14 for pi
V = 66.99 cm^3
Using the pi button
V = 67.02 cm^3
Step-by-step explanation:
The area of the base of the cone is the area of a circle
A = pi r^2
A = pi * 4^2 = 16 pi
The volume of a cone is given by
V = 1/3 Bh where B is the area of the base and h is the height
V = 1/3 (16 pi) * 4
V =64/3 pi cm^3
Using 3.14 for pi
V =66.9866666
Rounding to the nearest hundredth
V = 66.99 cm^3
Using the pi button
V =67.02064328
Rounding to the nearest hundredth
V = 67.02 cm^3
