An actin gene in humans is 92% identical to the homologous gene in mice. An actin gene in humans is 80% identica to the homologous gene in yeast. What does this say about how long ago these organisms had a common ancestor?

The volume of the pipe is 153.86

Explanation:

Given the thickness of the cylindrical pipe is 1.25 inch

Width is 6 inches

Length is 16 inches

Diameter = width – 2(thickness)

Diameter = 6 – 2(1.25) = 6 – 2.50 = 3.50 inches

Radius (r) = 3.50/2 = 1.75 inches

Volume is calculated by, V = 3.14 * (1.75)2 * 16

Volume = 153.86

Therefore, the volume of the pipe is 153.86
