Answer:
The 2nd one
Step-by-step explanation:
All we need to do is start with the volume formula. Then, input the volume and solve the equation for the radius. And double it to get the diameter.
V = (4/3)pi(r^3)
12114.7 = (4/3)pi(r^3) Divide both sides by (4/3) and pi
2893.64 = r^3 Take the cube root of both sides
14.25 = r
So the diameter is about 28.5 cm (14.25 x 2 = 28.5)
Answer:

Step-by-step explanation:
Start with the given

Divide the two on both sides to get

To find the mean, add up all the test scores and divide by the number of tests:
524/10 = 52.4.
