Answer

$18$

Work Step by Step

Graphing the given equations, we take $f(y)=2y^{2}$ (the curve on the right side) and $g(y)=0$ (the curve on the left). When $y\in[c,d]=[0,3]$, the area between the graphs is $A=\displaystyle \int_{c}^{d} [f(y)-g(y)]dy=\displaystyle \int_{0}^{3}2y^{2}dy=$ $=2\displaystyle \left[\frac{y^{3}}{3}\right]_{0}^{3}$ $=\displaystyle \frac{2}{3}(27-0)$ $=18$
