To find the circumference of a circle you use the formula C=pi*(radius*radius). If you know that the cuircumference is 6 pi, you first plug that in to solve for the radius.
6pi=pi*(r*r)
6pi/pi=(r*r)
Square root of(6pi/pi)=r
2.45=r
Then to find the area you use the formula A=pi*(r*r) which is
A=Pi*(2.45*2.45)
A=6pi or 18.85

The circumference formula is 2\pir and if the circumference is 6pi then the radius is 3. apply that to the area fromula ( \pir^2 ) and you get 9\pi

What is the volume of the solid?
Evgen [1.6K]

9514 1404 393

Answer:

  (9√3 -3π/2) ft^3 ≈ 10.88 ft^3

Step-by-step explanation:

The area of the hexagon is given by the formula ...

  A = (3/2)√3·s^2 . . . . for side length s

The area of the hexagonal face of this solid is ...

  A = (3/2)√3·(2 ft)^2 = 6√3 ft^2

__

The area of the circular hole in the hexagonal face is ...

  A = πr^2

The radius is half the diameter, so is r = (2 ft)/2 = 1 ft.

  A = π(1 ft)^2 = π ft^2

Then the area of the "solid" part of the face of the figure is ...

  A = (6√3 -π) ft^2

__

The volume is ...

  V = Bh . . . . . where B is the area of the base of the prism, and h is its height

  V = ((6√3 -π) ft^2)(3/2 ft) = (9√3 -3π/2) ft^3 ≈ 10.88 ft^3
