A. this is a geometric sequence.

according to y-coordinates =>

3, 6, 12, 24

have a T1 = 3 and ratio = 6/3 = 2

B. the formula = Tn = r. T(n-1)

T5 = 2. T4

= 2. 24 = 48 minutes

C. the formula : Tn = T1 . r^(n-1)

T9 = 3. 2^(9-1)

= 3. 2^8

= 3. 256

Which point on the number line represents the approximate volume of a cone with the radius of 3 units and a height of 4 units? U

alekssr [168]

Answer: Third red dot after 30 on the number line represents the approximate volume of a cone.

Step-by-step explanation:

Since we have have given that

Radius of cone = 3 units

Height of cone = 4 units

So, Volume of cone is given by

$Volume=\frac{1}{3}\pi^2\times h\\\\Volume=\frac{1}{3}\times 3.14\times 3\times 3\times 4\\\\Volume=37.68\ units^3$

Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.
