What is the exact volume of a sphere with a diameter of 18 cm? ______ cm3

1 answer:

6 0

The formula for volume of a sphere is (4/3)πr², with r being the radius. Since the diameter of the sphere is 18 cm, the radius is 18/2, which is 9. Now substitute the 9 for r so you have:

V=(4/3)π*9²

V=(4/3)π*81

V=108π

108π is the exact volume of the sphere.

How to solve -2(x+3)=8

Shtirlitz [24]

-2(x + 3) = 8

Multiply -2 with x and 3

-2x -6 = 8

Now add 6 to both sides

-2x -6 = 8
+6 +8

-2x = 16

Lastly divide -2 from both sides to find x

-2x = 16
—— —-
-2x -2x

X = -8

Divers in a competition are scored by an international panel of judges. The highest and the lowest scores are dropped. The total

Fudgin [204]

From the statements given in the problem, we can say that:

Final Score = (total of the remaining scores) * degree of difficulty * 0.6

Therefore:

97.2 = (total of the remaining scores) * 4.0 * 0.6

total of the remaining scores = 40.5

Therefore the judges could have scored which has a total of 40.5
