Diameter is 2r, or 18.8 ft
Circumference is 2*pi*r, or 59.1 ft
Last option is the correct answer.
Step-by-step explanation:
Given that
Let x stand for the solution a and y stand for the solution B
So,
According to statement that
30 gallons have to be made

Solution A contains 29 percent bromine => 0.29x
Solution B contains 53 percent =>0.53y
And the mixture of 30 gallons contains 45% bromine

Following equations will be used for solving the problem

Hence,
Last option is the correct answer.

In order to find out how much they both each pay, you would have to put two places in front of the percentage of the payment.
That would be 1953.08
