Exercise 12 Page 752

66Ï€ m^2

Practice makes perfect

The given solid is a cylinder.

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 3 and h with 8 into the formula, we can solve for S. Let's do it!

S=2Ï€ rh+2Ï€ r^2
S=2Ï€( 3)( 8)+2Ï€( 3)^2
â–¼
Simplify right-hand side
S=2Ï€( 3)(8)+2Ï€(9)
S=48Ï€+18Ï€
S=66Ï€

The surface area of the cylinder is 66Ï€ m^2.
