Answer:
the area is 254.47
Step-by-step explanation:
A=pi sign r²
d=2r
now we solve for the area
A=1/4 pi sign d²=1/4 times 3.14 times 18=254.47
The bill will be $100 bc the rate of it is .5 per text so basically all your doing is multiplying by 2
Okay, because 18% of 16 is 2.88, we can cross off C. and D. as an option.
Now, because it is a 27% acid solution of an unknown amount, B. is not correct because it says 0.21x, rather than 0.27x. Knowing this, we can safely say that The answer is Option A
