Exercise 17 Page 840

Use the formulas for the surface area and volume of a cylinder.

307.9 mm^3

The given solid is a cylinder.

The volume of a cylinder with the radius r and height h can be calculated by the following formula. V=π r^2 h Since we are given both the radius r and height h of the cylinder, we can substitute them into the formula and calculate V.

V=π r^2 h

r= 7, h= 2

V=π ( 7)^2 ( 2)

▼

Simplify right-hand side

Calculate power

V=π( 49)( 2)

Multiply

V=98π

Use a calculator

V=307.876080...

Round to 1 decimal place(s)

V≈ 307.9

The approximate volume of the given cylinder is 307.9 mm^3.
