Answer:
The current area of the circle is 81π in².
They want to " 'decrease' " the radius to 9 in.
First, find the current radius for the current circle.
Areas of circle = πr²,
81π = πr²
First, divide π from both sides of the equation:
(81π)/π = (πr²)/π
r² = 81
Isolate the variable, r. Root both sides of the equation:
√(r²) = √(81)
r = √( 9 * 9) = 9
The radius currently is 9 in.
The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).
