Lara found the volume of a sphere with a diameter of 10.

Paraphin [41]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=10/2=5\ units$ ----> the radius is half the diameter

substitute

$V=\frac{4}{3}\pi (5)^{3}$

$V=\frac{500}{3}\pi\ units^{3}$
