The volume of this sphere is 972 pi cubic inches. What is its radius? A sphere.

Recall the formula Sphere Volume = four-thirds pi r cubed.
7 inches
9 inches
108 inches
324 inches

   volume of a sphere = ⁴/₃ πr³

⇒      972π in³  = ⁴/₃ πr³

            729 in³ = r³

                   r    = 9 in

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
