Step-by-step explanation:
We have,
Height of cone, h = 12.7 m
Circumference of base, C = 18.9 m
The base of a circular cone is circular. The circumference of circle is given by :
[tex]C=2\pi r[/tex]
r is radius
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{18.9 }{2\pi}\\\\r=3\ m[/tex]
The volume of a right circular cone is given by the formula as :
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
[tex]V=\dfrac{1}{3}\times 3.14 \times 3^2\times 12.7\\\\V=119.634\ m^3[/tex]
