Janine wants to paint just the sides of a cylindrical pottery vase that has a height of 45 cm and a diameter of 14 cm. To the nearest whole number, find the number of square centimeters she will need to paint. Explain the method you would use to find the lateral area.
Lateral Area: 2π * r * h
2π * 7 * 14 = 196π = 615.75 cm^2
 
Am I doing it correctly? If so what should be my next step?

    Looks good, except the h=45, not 14

    2π * 7 * 45 = 630π = 1978.2cm^2 then would that be my final answer?

    not bad, except that you did not follow instructions:
<u>To the nearest whole number</u>
Oh, that and the fact that
2π * 7 * 45 = 1979.2
You apparently approximated π by 3.14
