What is the volume of the cone?​
lina2011 [118]

Answer:

The volume of the cone is 75.36 cm³

Step-by-step explanation:

The rule of the volume of a cone is V = \frac{1}{3} π r² h, where

  • r is the length of the radius of its base
  • h is the height of the cone

In the given figure

∵ The length of the radius of the cone is 3 cm

∴ r = 3 cm

∵ The length of the height of the cone is 8 cm

∴ h = 8 cm

→ Substitute the values of r and h in the rule of the volume above

∵ π ≅ 3.14

∵ V = \frac{1}{3} (3.14)(3)²(8)

∴ V = 75.36 cm³

∴ The volume of the cone is 75.36 cm³

This figure is 1/4 of a circle.
drek231 [11]

For this case we have that by definition, the perimeter of a circle is given by:

C = 2 \pi * r

Where:

r: It is the radius of the circle.

According to the figure, it is observed that the radius of the circle is 2. Then:

C = 2 \pi * 2\\C = 2 * 3.14 * 2\\C = 12.56 \ in

Let's remember that we have a quarter circle:

C = \frac {12.56} {4}\\C = 3.14

We round and we have that the correct option is 3.1 \ in

Answer:

Option A
