2. Multiply both sides by 6:
x = 12
Start with the given formula for the surface area of a sphere.

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.


The answer rounded to the nearest hundredth is 84.65.
Consider the number 84.647.
If we multiply this number by 1000, the result is 84647 which has 7 in its one's place.
Also, note that the value of the digit in the ones place is 4, which is half of 8, the value in the tenths place.
The remaining digit in the tenths place is 4.
Hence, the correct answer is 84.65 rounded to the nearest nundredth.
