The base of a cylinder has a radius of 9 cm. The cylinder is 12 cm tall. What is the approximate LATERAL area of the cylinder? Use 3.14 and round your answer to the nearest whole number.

The lateral area of the cylinder is 678 cm^2 to the nearest whole number

Step-by-step explanation:

Mathematically , the lateral area of a cylinder can be calculated using the formula

A = 2 π r h

where r is the radius = 9cm and h is the height = 12 cm

we are told to use a value of 3.14 for π

Thus the lateral area A is thus = 2 * 3.14 * 9 * 12 = 678.24 which is 678 cm^2 to the nearest whole number

14

step-by-step explanation:

14 x 3 = 42
