How many cubic inches of material do you need to make a solid rubber ball with diameter
of 3

Step-by-step explanation:

What we're looking for here is the volume of this ball, which is the volume of a sphere:

If our diameter is 3, then the radius is 1.5:

In terms of π, the solution is

which can also be expressed as

Or if you have to multiply in the pi, the solution is

V = 14.14 cubic inches

What is asked in the problem is simply the volume of the solid rubber ball.

Step-By-Step:

The volume of sphere given the diameter may be calculated by,

                              V = πd^3 / 6

Substituting the given value of diameter, 

                              V = (π x 3³) / 6 = 9π/2 or 14.14

Nonetheless, one needs approximately 14.14 in³ of material. 

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
