We can use the formula for the area of circle which is A = πr².
Find the diameter by dividing 7 and 2 which you get 3.5.
Substitute with the given values; A = (3.14)(3.5)².
Solve for the exponent; A = (3.14)(12.25).
Multiply; A = 38.465.

Answer: Employers have a responsibility to clearly communicate hazards and mark all hazards with the appropriate warning symbols
Explanation:
The statement that best describes why they display the symbol and the biohazard marking is because employers have a responsibility to clearly communicate hazards and mark all hazards with the appropriate warning symbols.
Since the boxes are labelled as hazardous, accidents can be prevented as one will clearly be aware not to go close to the hazard. Also, in some cases if an accident occur without people knowing that a hazard is there, the employer may end up paying a hefty fine for this and this has been prevented with the prior warnings.
