Given that Sheena's ball is a sphere, its volume can be obtained by using the formula: V_ball = (4/3)*pi*r^3, where, r is the radius of the sphere. Since the ball is 24 cm across, this means that the radius is half of the diameter which is equal to 12 cm. Thus, the volume of the ball is equal to 7238.2295 cm^2.

Are there answer choices? The only thing you can see change is the size and the pattern slightly changed.
<span>Having more lung capacity is advantageous because the lungs can expand more. More air in the lungs will fill all the alveoli (air sacs in the lungs) and allow more oxygen to enter the bloodstream via the capillaries that surround the air sacs. Excess waste (such as carbon dioxide) is also transferred from the blood to the air to be exhaled. As lungs fill, more gas exchange can occur.</span>
