If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when c is 2?

1 answer:

7 0

Direct variation has the for y=kx (inverse variation has the form y=k/x)

Since we are given a point we can solve for the constant of variation, k

48=6k so

k=8 so our equation is:

y=8x so

y(2)=8(2)

y(2)=16

So y=16 when x=2

Radius of cylinder = 5 cm

Kisachek [45]

Answer:

C 1055 04 cm

Step-by-step explanation:

We don't need to see the figure, since we know for sure the cone fits into the cylinder (smaller diameter and height).

So, we first need to calculate the volume of the cylinder, which is given by the formula:

VT = π * r² * h

VT = 3.14 * 5² * 16 = 3.14 * 400 = 1,256 cubic cm

Then we calculate the volume of the cone, which is given by:

VC = (π * r² * h)/3

VC = (3.14 * 4² * 12)/3 = (3.14 * 192)/3 = 200.96 cu cm

Then we calculate the void space left inside the cylinder by subtracting the volume of the cone from the volume of the cylinder:

NV = VT - VC = 1,256 - 200.96 = 1,055.04 cu cm
