Best ResponseYou've already chosen the best response.0lol nah...its alright....then what u wanna do is convert theta into degree (cuz this equation will let u find theta in 'radians') to do that...u follow this eq. dw:1358256989692:dw

Best ResponseYou've already chosen the best response.0theres a formula for this ( angle/360 degrees ) = ( arclength/ circumference ) so substitute: x /360 = 5.5/14pi 14pi bcuz "Circumference = 2pi(radius)" so 2pi(7)= 14pi x= ((360)(5.5))/14pi x= 1980/14pi or 990/7pi or 45.02 degrees ^.^
