The volume of the cone shown is 5 cubic inches. What is the height of a cone with the same base diameter but a volume of 10 cubi
MaRussiya [10]

Answer:

The height of the second cone is 2 <em>h</em>₁.

Step-by-step explanation:

The volume of a cone is:

V=\pi\ r^{2}\frac{h}{3}

The volume of the first cone is, <em>V</em>₁ = 5 in³.

The volume of the second cone is, <em>V</em>₂ = 10 in³.

The two cones have the same base diameters.

This implies that the two radii are same, i.e. <em>r</em>₁ = <em>r</em>₂.

Compute the height of the second cone as follows:

   r_{1}=r_{2}

\frac{3\cdot V_{1}}{\pi\ h_{1}}=\frac{3\cdot V_{2}}{\pi\ h_{2}}

  \frac{V_{1}}{h_{1}}=\frac{V_{2}}{ h_{2}}

  \frac{5}{h_{1}}=\frac{10}{h_{2}}

  h_{2}=2\ h_{1}

Thus, the height of the second cone is 2 <em>h</em>₁.

If possible may someone help me please?
Orlov [11]

Answer:

Given, ∠MNP=107 degree.

Therefore, ∠QPN= 107 degree. [as, MN=PQ]

We know, sum of four angles of a quadrilateral is 360 degree.

And as MN=PQ, ∠NMQ=∠MQP.

Therefore, ∠MQP= {360 degree-( 107degree+ 107 degree)}/2

                             =( 360 degree-214 degree)/2

                            = 146 degree/2

                            =73 degree.

hope this will help you.
