In this paper, we develop several Euclidean operator radius inequalities of$d$-tuple operators, as well as the sum and the product of $d$-tuple operators.Also, we obtain a power inequality for the Euclidean operator radius. Further,we develop Euclidean operator radius inequalities of $2\times 2$ operatormatrices whose entries are $d$-tuple operators.
