WebOct 31, 2024 · Solution. Step 1. If we let A represent the area of an ellipse, then we can use the statement “area varies jointly as a and b ” to write. A = k a b. Step 2. To find the constant of variation k, use the fact that the area is 300 π when a = 10 and b = 30. 300 π = k ( 10) ( 30) 300 π = 300 k π = k. Step 3.
