For a party, three solid cheese balls with diameters of 2 inches, 4 inches, and 6 inches, respectively, were combined to form a single cheese ball. what was the approximate diameter, in inches, of the new cheese ball? (the volume of a sphere is 43πr343πr3, where r is the radius.)

Here we need to find the volume of each spherical ball using the given values of the diameter and then we combine those values and find the diameter .

For the first ball, diameter is 2 inches, so radius =1 inches

For the second ball, diameter is 4 inches, so radius = 2 inches

For the third ball, diameter is 6 inches, so radius =3 inches.

Now we use the given formula of the volume of sphere.

Total volume = 4.2 +16.755 + 37.7 =58.655

Now we have the volume and using the given formula of volume of spher, we can find out the radius .

So diameter = 2 * 2.4 = 4.8 inches

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
