The volume of the cone is 57 cm³.
Solution:
Given data:
A = Radius of the cone (r) = 3 cm
C = Height of the cone (h)
= Double length of A
= 2 × 3 cm
C = 6 cm
The value of π = 3.14
Volume of the cone:
[tex]$V=\frac{1}{3} \pi r^2 h[/tex]
[tex]$V=\frac{1}{3} \pi A^2 C[/tex]
[tex]$V=\frac{1}{3} \times 3.14 \times 3^2 \times 6[/tex]
[tex]$V=56.52[/tex] cm³
Round to the whole number, we get
V = 57 cm³
The volume of the cone is 57 cm³.
