Question

The formula of finding the volume of a cone is V=1/3π^2h.The radius of a cone is 5 cm and the height of a cone is 10 cm. What is the approximate volume of the cone?

A.)2,356 cm^3
B.)52 cm^3
C.)262 cm^3
D.)524 cm^3

Answer 1

The correct formula is V=1/3 × pi × r^2 × h
Simply substitute r = 5, and h=10
the approximate volume is 262 cm^3...
the answer is C

Answer 2

answer is C.)262 cm^3

V=1/3πr^2h
V=1/3 x 3.14 x 5^2 x 10= 261.67 cm^3
