In circiar measure the value of the angle `11^(@)15` is(वृत्तीय माप में `11 ^(@) 15 ^(@)` कोण का मान क्या होगा )A. `(pi^(e))/(16)`B. `(pi^(e))/(8)`C. `(pi^(e))/(4)`D. `(pi^(e))/(12)`

Answer» Correct Answer - a
`11 ^(@)15^(@)=11+(15)/(60)=11+(1)/(4)=(45 ^(@))/(4)`
We know `pi` radian `=180^(@)`
`1 ^(@)=((pi)/(180))` radian
`(45^(@))/(4)=(pi)/(180^(@))xx(45^(@))/(4)=( pi^(@))/(1 6 )`
