A correlation coefficient of .70 indicates a strong positive relationship between two variables. The coefficient of determination (r squared) is the proportion of the variation in one variable that can be explained by the other variable. To find r squared, simply square the correlation coefficient, which in this case is .70^2 = .49, or 49%. Therefore, about 49% of the variations in one variable can be explained by the variations in the other variable.
