Question

Estimate the volume of each ball. Use the formula

Answer 1

Answer:

Vtennis = 134 [cm^3]; Vgolf = 40.76 [cm^3]

Explanation:

To solve this problem we must have the values of the radius or diameters of each of these balls, therefore performing an internet search we can appreciate that the diameters of these balls are:

Dt = 6.35[cm]

Dg = 4.27[cm]

But we need the radius, and we know that the radius is equal to the half of the diameter.

Rt = 3.175 [cm]

Rg = 2.135 [cm]

Now replacing this values in the given equation:

$V = \frac{4}{3} *\pi *r^{3}\\ V_{tennis}= \frac{4}{3} *\pi *(3.175)^{3}\\ V_{tennis}= 134.06[cm^3]\\\\ V_{golf}= \frac{4}{3} *\pi *(2.135)^{3}\\V_{golf}= 40.76 [cm^3]$
