A cone has a diameter of 12 centimeters and a height of 9 centimeters. Using 3.14 for pi, find the
volume of the cone to the nearest tenth.

Answers

Answer 1

A cone has a diameter of 12 centimeters and a height of 9 centimeters. The volume of the cone would be 2034.72 cubic cm.

How to find the volume of a right circular cone?

Suppose that the radius of considered right circular cone be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

A cone has a diameter of 12 centimeters and a height of 9 centimeters.

Radius = 12/2 = 6cm

Height h = 9 cm

The volume of the cone

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

[tex]V = \dfrac{1}{3} \times 3.14 \times 6^3 \times 9\: \rm unit^3\\\\V = 3.14 \times 648\\\\V = 2034.72 cm^{3}[/tex]

Hence, The volume of the cone would be 2034.72 cubic cm.

m=2/13

Step-by-step explanation:

Given function:

-5m=8m-2

Subtract middle value from both side:

[tex]-5m-8m=8m-2-8m[/tex]

Combine like terms:

[tex]-13m=-2[/tex]

Divide both sides by the same term:

Answers

9514 1404 393

Answer:

  h = 2m

Step-by-step explanation:

We can put the given values into the area formula and solve for the missing one.

  A = (1/2)(b1 +b2)h

  7m²= (1/2)(3m +4m)h

  7m² = (7/2)m·h

  (7m²)(2/(7m)) = h = 2m

The missing height is 2 m.
