Exercise 28 Page 648

Use the formulas for the surface area.

about 1885.0 m^2

Practice makes perfect

The given solid is a cylinder with a radius of 15 meters and a height of 5 meters. To calculate the surface area of a cylinder, we can use the following formula. S=2Ï€ rh+2Ï€ r^2 In this formula, r is the radius of the base and h is the height of the cylinder. Substituting r with 15 and h with 5 into the formula, we can solve for S. Let's do it!

S=2Ï€ rh+2Ï€ r^2
S=2Ï€( 15)( 5)+2Ï€( 15)^2
â–¼
Simplify right-hand side
S=2Ï€( 15)(5)+2Ï€(225)
S=150Ï€+450Ï€
S=600Ï€
S=1884.955592...
S≈ 1885.0

The surface area of the cylinder is about 1885.0 m^2.
