Are you sure that the radius is 3.14? Cause 3.14 is pie
So it's asking you to solve the equation for the letter R, but there are no values. You can still solve, however, because if you rewrite it as. D = R × T, then you can see that if you divide by T you get D ÷ T = R, which is the letter they wanted. This would be your answer, I hope this helps!
"A chemist is using 336 millilitres of a solution of acid and water."
This sentence implies that the solution only contains acid and water.
Now, we are told:
"15.6% of the solution is acid."
What is 15.6% percent though, as a decimal?
Well, 15.0% is actually equal to 0.15 as a decimal. 0.6% is actually 3/5 of 1%, which in turn is 3/5 of 0.010 which is 0.006 as a decimal.
So, we now know that 15.6% is actually equal to 0.156 as a decimal.
Let's multiply 0.156 by 336 to get our answer.
0.156 x 336 = 52.4 (rounded to the nearest tenth)
There are 52.4 millilitres (to the nearest tenth) of acid in the solution.
