In a stadium an athlete is running on a circular path with uniform speed during a practice session. The angle covered by him during one second is found to be 10^@ by a coach observing him from the centre of the circular track. What would be the measure of angle (in degrees) described by the athlete by an observer standing on the circle? किसी स्टेडियम में एक एथलीट अभ्यास सत्र के दौरान एक समान चाल से वृत्ताकार पथ पर दौड़ रहा है | वृत्ताकार पथ के केंद्र से उसे देख रहे एक कोच की आँखों से उसके ( एथलीट ) द्वारा एक सेकंड में तय किया गया कोण 10. है | वृत्त पर खड़े प्रेक्षक की आँखों से एथलीट द्वारा बनाए गए कोण का माप क्या होगा ?
