Find the volume of the cone. Use the symbol pi in the calculator. Round to the tenths
place.
3
m

  615.8 m³

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = (1/3)πr²h

For your given radius and height, the volume is ...

  V = (1/3)π(14 m)²(3 m) = 196π m³

  V ≈ 615.75216 m³ ≈ 615.8 m³

The π button on the calculator uses a value slightly larger than 3.14, so an answer with 3.14 for pi will be incorrect.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
