A cylinder has a height of 6 inches and a radius of 5 inches. What is its volume? Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

Answer 1

V= h(pi)(r^2)

= 6(3.14)(5^2)

= 6(3.14)(25)

= 150(3.14)

=471 in^3= Volume of a cylinder with height = 6 inches and radius 5 inches

Exactly 471 cubic inches if you use pi =3.14

(But if you used a calculator with a pi key, and closer value of pi = 3.141593...

then round off the volume to 471.29 in^3 = an approximation, rounded to 2 decimal places)
