Answer:

[tex]678 cm^2[/tex]

Explanation:

We'd use the formula below to find the lateral area of the cylinder:

[tex]A = 2*\pi*r*h[/tex]

Note:

  • r represents radius
  • h represents height
  • Use 3.14 for pi

[tex]A = 2*3.14*9*12[/tex]

[tex]A = 2*3.14*9*12 = 678.24[/tex]

Area = 678.24

Round to the nearest whole number:

678.24 -> 678

Our answer would be [tex]678 cm^2[/tex]

The lateral area of the cylinder given radius, 9 cm and height, 12 cm is 678 cm²

Given:

Radius, r = 9 cm

Height, h = 12 cm

The lateral height of the cylinder, = 2 × π × r × h

= 2 × 3.14 × 9 cm × 12 cm

= 678.24 cm²

Approximately, 678 cm² to the nearest whole number

Therefore, the lateral area of the cylinder given radius, 9 cm and height, 12 cm is 678 cm²
