Answer:
<em>Mark used 6.43 megabytes of data.</em>
Step-by-step explanation:
The given equation is: 
, where 
is amount of data used in megabyte.
For finding the amount of data Mark used, <u>we need to solve the above equation for </u>.
First subtracting 5.25 from both sides, we will get.....
Now, dividing both sides by 0.3 ...........
<em>(Rounded to the nearest hundredth)</em>
Thus, Mark used 6.43 megabytes of data.
<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51
a = 85 and b = 51</span>
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
