Answer:

78

Step-by-step explanation:

angle ACD + angle DCB = 180   (Angles on straight line)

4x + 2 + 3x + 3 = 180

7x + 5 = 180

7x = 180-5

7x = 175

x = 175 / 7

x = 25

angle DCB = 3x +3 = 3*25 + 3 = 75 +3 = 78

A model of a volcano has a height of 12 in. , and a diameter of 12 in. What is the approximate volume of the model? Use 3. 14 to
jenyasd209 [6]

The approximate volume of the model will be

v=452.33 inch^{2}

<h3 /><h3>What is the approximate volume of the model? </h3>

It is given that

Height of the volcano =12 inch

Diameter of the volcano= 12inch=r=6inch

So the volume of the model will be =

=\dfrac{1}{3\\} \pi \times r^{2} \times h

= \dfrac{1}{3} \pi \times (6)^{2} \times 12

v=452.33inch^{2}

Thus the approximate volume of the model will be  v=452.33 inch^{2}

To know more about the volume of the cone follow
