Question

Find the volume of the figure. Use 3.14 for π. If necessary, round your answer to the nearest tenth.

Answer 1

190.85 ft²

Explanation:

Solution Given:

Volume of cone=⅓*πr²h

where r is radius and h is height.

For Question:

r=4.5 ft

h=9ft

Now

Substituting value in above formula:

we got

Volume of cone = ⅓*π*4.5²*9=190.85 ft²

Answer 2

• 190.8 ft³

-------------------------

Use formula for the volume of a cone:

• V = πr²h/3

Substitute 3.14 for π, 4.5 ft for r and 9 ft for h and calculate:

• V = 3.14*4.5²*9/3
• V = 190.755

Round to nearest tenth:

• V ≈ 190.8 ft³
