The formula for the surface area of a cylinder is:
As you probably know, the diameter is 2 times the radius, so by dividing the diameter, 34, by 2, we get 17 to be the radius.
Now, just plug the numbers in:
f(x) = x2 ÷ 3 + x
f(6)
Replace X with 6 then follow order of operations.
6^2 / 3 + 6
6^2 = 36:
36 / 3 + 6
36 /3 = 12:
Add:
12 + 6 = 18
The answer is 18
Since Doug’s brother has double the amount of Doug we can just multiply the amount Doug has by 2.
