Please answer that and help me!! I’ll give you brainliest if u answer it good.

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).
