The radius of the balloon given the information in the question is 8.98cm.
<h3>What is the radius of the balloon?</h3>
The first step is to determine the volum of the balloon.
Volume = 81π cm^3 x 12 = 972π cm^3
Now, determine the radius using this formula:
∛[Volume / (4/3π )]
∛[972π cm^3/ (4/3π )] = 8.98cm
Here is the complete question:
Andy is blowing up a spherically shaped balloon. If he is able to blow 81π cm^3 of air with every breath, it takes him 12 breaths to fully inflate the balloon. What is the radius of the balloon?

10/12 in simplest form is 5/6.
Equivalent ratios would be 15/18, 20/24, and 25/30.
The rest is easy, give it a try.
<u>1) Rewrite it in the form a^2-2ab+b^2, where a=11m and b=9</u>
(11m)^2-2(11m)(9)+9^2
<u>2) Use Square of Difference: (a-b)^2=a^2-2ab+b^2</u>
(11m-9)^2
<u>Your answer is (11m-9)^2</u>
