"একটি বিন্দুর অবস্থান খুঁজুন যা (1,3) এবং x-অক্ষ থেকে সমান।"

Statement I int_0 ^ (npi + t) | sinx | dx = (2n + 1) -cost, (0 leq t leq pi) Statement II int_a ^ bf (x) dx = int_a ^ ef (x) dx + int_e ^ bf (x) dxint_0 ^ (na) f (x) dx = nint_0 ^ af (x) dx "if" f (a + x) = f (x)

Calculate the volume of a sphere of radius (3.0pm0.1) cm, if the error quoted is the standard deviation in the measurement. [Hint: V=(4pi)/(3)r^(3),((deltaV)/(V))^(2)=3^(2)xx((deltar)/(r))^(2) ]
