A geologist is mapping geological formations and discovers a sedimentary layer that grows at a rate proportional to its thickness. If the layer grows from 50 meters to 200 meters over 200 years, assuming exponential growth, find the annual growth rate. Use the formula \( N(t) = N_0 \times e^{rt} \). Calculate \( r \).
