Which of the following represents the volume V of a right circular cone as a function of the radius r of its circular base, when the height of the cone is twice the radius of the base circle? => 2 π r 3 or 1 3 π r 3 or 2 3 π r 3 or 4 3 π r 3..

The circle whose radius is 1 unit whose centre is the origin of a rectangular co-ordinate system is called the unit circle. 1. cos q = x. 2. sin q = y. 3. tan q = y/x. 4. sec q = 1/x. 5. cosec q = 1/y. 6. cot q = x/y. The six functions of q defined by the above equation are..

RNA serves the following functions: mRNA has a significant role in genetic code. tRNA is responsible for transferring amino acids to the site of protein synthesis (ribosomes). rRNA assembles the amino acids into a polypeptide chain. It also serves as a primer for replic..
