Answer:

Step-by-step explanation:

Formula

V = (1/3) pi * r^2 * h          Substitute the givens into the formula

Givens

V = ?

pi = 3.14

r = 3 in

h = 18 in

Solution

V = 1/3 * 3.14 * 3 * 3 * 18

V = 169.56

Answer

V = 169.56 in^2

Question -:

A cone has a radius of 3 inches and a height of 18 inches what is the volume?

Explanation -:

Given:

  • Radius of a cone = 3 inches
  • Height of a cone = 18 inches

Need to find :

  • Volume of a cone

Solution :

We know,

[tex] \small\boxed{ \sf{ Volume_{(cone)} = \dfrac{1}{3} × π × {r}^{2} × h}}[/tex]

Where,

  • r stand for radius
  • h stand for height
  • Assuming π as 3.14

[tex] \small\rm Volume_{(cone)} = \dfrac{1}{\cancel{3}} × 3.14 × { \cancel3} × 3 × 18[/tex]

[tex] \small\rm Volume_{(cone)} = 3.14 × 3 × 18 = 169.56 \: inches[/tex]

  • Hence the volume of the cone is 169.56 inches.
