In scientific notation, the radius of each bacterium in a petri dish is 3.15 × 10-7 meter. the radius of the bacterium written as a decimal number in standard form is meters?

Radius of bacterium is given as

now we know that

now using the above value

so above is the standard form of the representation.

1 the 4 is sig

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
