Question

Which of the equations listed below are linear equations? Equation I: C=2*3.14*r Equation II: A = 3.14*r^2 Equation III: V = 4/3*3.14*r^3

Answer 1

Equation I: C=2*3.14*r

Explanation:

A linear equation is an equation whose highest exponent on the variable is 1.

C=2*3.14*r.................Exponent of 1

A = 3.14*r^2...............Exponent of 2

A = 3.14*r^2...............Exponent of 3
