#(7pi)/18#

Explanation:

We know:

#360^circ = 2pi " radians " #

#=> 1^circ = (2pi)/360 " radians " #

#=> 70^circ = (2pi)/360 * 70 = (7pi)/18 " radians "#

#70° = 1.22173 " radians"#

Explanation:

#pi " radians "= 180°#
#=> 70° = (70/180) pi " radians"#
#= (7/18) pi " radians"#
#= 1.22173 " radians"#

#"Remember that the circumference of a circle with radius r"#
#"is equal to "2 pi r". So one circle = 360 ° = " 2 pi " rad, hence"#
#180° = pi " rad."#

#"And "pi" is known to be equal to 3.1415926535..."#
