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? U se 3.14 and round your answer to the nearest whole number.
1 answer:
Answer:
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
