We'll use the Pythagorean Theorem
130^2 = side^2 +50^2
side ^ 2 = 16,900 -2,500
side ^ 2 = 14,400
side = square root (14,400)
side = 120 feet

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
