when a spherical balloon is filled with air, it has a radius of 3 inches. what is the estimate for the volume of air in the ball
Crazy boy [7]

The volume of a sphere is given by the equation V=\frac{4}{3} \pi r^{3}, where V is the volume and r is the radius.


To answer this question, simply plug the correct values into the equation:

V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976


The volume of the air in the balloon is about 113.0976 in3.


Hope this helps!!

What is the product of 0.51 × 0.24?<br><br> 0.1224<br> 1.124<br> 11.24<br> 1124
natima [27]
0.52 x 0.24 means "about a half times 0.24". Given the multiple choice answers, the correct answer is therefore 0.1224 (since this is the only one smaller than 0.24).

Proof:
0.50 × 0.24 = 0.12
0.01 × 0.24 = 0.0024
And therefore 0.51 × 0.24 = 0.12 + 0.0024 = 0.1224
