CORRECT!
Again, real quantities have + values and virtual quantities have - values. When the center of curvature is on the right side where the refracted light really goes after passing through the lens, the R is +.
When the center of curvature is on the left side where the refracted light does NOT really go after passing through the lens, the R is -.
Also, since our convention places the real object to the left of the lens, the first surface the light hits is the left surface, which has radius of curvature R1.
The second surface the light hits is the right surface, which has radius of curvature R2.
Here, the center of the left side ) is on the left side where the refracted light does NOT really go after passing through the lens, so R1 is -.
However, the center of the right side ( is on the right side where the refracted light really goes after passing through the lens, so R2 is +.
