A cylinder has a base diameter of 16cm and a height of 19cm. What is its volume in cubic cm, to the nearest tenths place?
elena-14-01-66 [18.8K]

Answer:

V = 3216.9 cm^{3}

Step-by-step explanation:

Volume of a cylinder = π r^{2} h

We are given diameter, 16cm, and half of it is the radius

r = 8cm

h = 19cm

Substitute the values into the equation

V = π * 8^{2} * 19

V = 3216.9 cm^{3}

noname [10]

Answer:

He can build 20 houses. He will have 5 left over.
