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 radiush represents heightUse 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
