The answer is to simplyfly
B is correct.
A. 5(x-2)= 5x-10
B. 4(x+3)= 4x + 12
C. 3(x+1)= 3x+3
D. 2(x+7) = 2x + 14
Volume of a cylinder is:
π x radius² x height
Radius = width / 2 = 2
so:
π x 2² x 8 = 32π = 100.53
I'm guessing the answer is "32in" because that's the only answer that matches the answer 32π. Maybe the units are wrong in the question.
F - because you must move the decimal place 9 spaces to the left in order to have only a single digit in front of the decimal place. (There can never be more than one otherwise it is no longer scientific notation.
