A cylinder has a radius of 30.8 centimeters and height of 20.5 centimeters. Which measurement is closest to the lateral surface area of the cylinder in square centimeters

The answer to your question is 9923 cm²

Step-by-step explanation:

Data

radius = 30.8 cm

height = 20.5 cm

Surface area = ?

Process

1.- Write the formula to calculate the surface area of a cylinder

SA = 2πr² + 2πrh

2.- Substitution

π = 3.14

SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)

3.- Simplification

SA = 5957.459 + 3965.192

4.- Result

SA = 9922.65 cm² or SA = 9923 cm²

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
