Question

Anyone??????????????

Answer 1

the height is approximately 27.2837

Explanation:

V=
`\pi/3r^(2)h`

350=
`\pi /3 (3.5)^(2)h`

350=12.25
`\pi /3 h`

350/12.25=
`\pi /3h`

28.571/(
`\pi /3`=
`h`

Answer 2

27.28 m

Explanation:

You are given the formula of the volume of a cone and you are also given the volume and the diameter of the cone.

Since the volume uses the radius of the cone, first convert the diameter 7 to the radius by div'g by 2. The radius of the cone is 3.5.

Now substitute 3.5 for r and set the equation equal to the volume of 350.

1/3
`\pi`(3.5)^2(h) = 350

Evaluate the exponent.

1/3
`\pi`(12.25)(h) = 350

Multiply 1/3, pi, and 12.25 together.

12.83h = 350

Divide both sides by 12.83.

h = 27.28
