Answer:

y = 225

Step-by-step explanation:

since y and x are directly proportional the equation relating them is

y = kx ← k is the constant of proportionality

to find k use the given condition y = 288 when x = 32

k = \frac{y}{x} = \frac{288}{32} = 9

y = 9x ← is the equation of proportionality

when x = 25, then

y = 9 × 25 = 225

Answer:

22.88 cm^3

Step-by-step explanation:

The volume of a sphere formula is (4/3)*pi * (radius)^3

Since the diameter is 5.08cm, we divide by 2 to find the radius which is 2.54 cm.

Also because of the fact that 2/3 is showing outside the cone, that means 1/3 is inside the cone. Therefore, we have to multiply the volume by 1/3.

We have:

Volume = (4/3) * pi * (2.54)^3 * (1/3)

= 22.88 cm^3
