Bacteria live in groups called colonies. Colonies are usually circular. The diameter of a particular bacterial colony is 12 mm. The circumference of a circle is equal to pi (3.14) times the diameter (C = pi times the diameter)1.What is the circumference of the colony?
2.What is the radius of the colony

Answers

The circumference would be 37.68 mm, and the radius is 6 mm.

Answer:

the circumference is

3.14 times the diameter or

3.14 x d

since d is 8 the equation becomes

3.14 x 8 = 25.12 mm in circumference.

Which statement BEST summarizes Darwin's explanation for these differences?A) Random mutations caused the shape of the shells to fluctuate periodically.
