U should either multiply 8% by 16ml hope i helped. :)
I would say that the answer is D 21.63
Answer:
discrete and quantitative I think
So the formula you have to do is A= (pie)(radius)(squared)
divide 6.7 by 2 to find the radius which is 3.35
now do 3.35 * 3.35 ( we are squaring it) which = 11.225
now 11.225 times PIE is 35.264377537
so the answer is 35.264377537
hope that helped!
