Question

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

Answer 1

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,

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

Where,

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

`\small\rm Volume_((cone)) = \frac{1}{\cancel{3}} × 3.14 × { \cancel3} × 3 × 18`

`\small\rm Volume_((cone)) = 3.14 × 3 × 18 = 169.56 \: inches`

• Hence the volume of the cone is 169.56 inches.

`\rule{74mm}{8pt}`

Answer 2

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
