Find the missing height of the cone. Volume= 118π ft3 Diameter= 2/3

grin007 [14]

Answer:

11 ft

Step-by-step explanation:

The equation for the volume of a cone is:

V = 1/3(3.14)r^2h

V = 414.48

r = 6

Plug in those values and solve for h:

414.48 = 1/3(3.14)(6)^2h

414.48 = 37.68h ; divide both sides by 37.68

11 = h

The missing height is 11ft.

Answer:

C log3(√((x -4)/x)

Step-by-step explanation:

The applicable rules of logarithms are ...

log(a/b) = log(a) -log(b)

log(a^n) = n·log(a)

The base is irrelevant, as long as all logs are to the same base.

$\dfrac{1}{2}(\log_3{(x-4)}-\log_3{(x)})=\dfrac{1}{2}\log_3(\dfrac{x-4}{x})=\boxed{\log_3\left(\sqrt{\dfrac{x-4}{x}}\right)}$

Rashid [163]

Answer:

The ratio of sixth-grade students to fifth-grade students on the team was 7 : 8.

Step-by-step explanation:

Given:

The girl's basketball team had 8 fifth-grade students and 7 sixth-grade students.

Now, to find the ratio of sixth-grade students to fifth-grade students on the team.

Number of fifth-grade students = 8.

Number of sixth-grade students = 7.

Now, to get the ratio of sixth-grade students to fifth-grade students on the team :

$Number\ of\ sixth-grade\ students:Number\ of\ fifth-grade\ students$

$=7:8.$

Therefore, the ratio of sixth-grade students to fifth-grade students on the team was 7 : 8.
