What is the volume of a cone that has a height of 7 mm and a radius of 3 mm?

1 answer:

7 0

<span>So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.</span>

Answer:

The answer is 6z-28

Step-by-step explanation:

20 - 3[4(z+1) - 6(z-2)]

= 20 - 3(4z+4-6z+12)

= 20 - 3(16 - 2z)

= 20 - 48 + 6z

= 6z - 28

State what additional information is required in order to know that the triangles are congruent by SAS

zalisa [80]

<h3>You are correct. The answer is the second choice.</h3>

BC = JC by the single tickmarks shown

CD = CD because of the reflexive property

The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).

See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
