Answer:
[tex]v = 2064.2 {cm}^{3} [/tex]
Step-by-step explanation:
we first consider the formula for the volume of a sphere
[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
we were given diameter of 15.7cm.
we can find the radius by dividing the diameter by 2
because two times a radius makes a diameter.
[tex] \frac{15.7}{2} = 7.9cm[/tex]
we have the radius as 7.9cm.
and we know pi (π) to be 3.14 or 22/7.
but in this case, we use 3.14.
now let's substitute the values in the formula
[tex]v = \frac{4}{3} \times 3.14 \times {7.9}^{3} [/tex]
and we will get
[tex]v = 2064.19 {cm}^{3} [/tex]
but the nearest 10th will be
[tex]v = 2064.2 {cm}^{3} [/tex]
