Darren's model is wrong because he multiplied the fractions when he should have subtracted.
4/5 • 1/2 = 4/10

4/5 - 1/2
8/10 - 5/10 = 3/10

The correct model would be 3/10.

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

The formula I = PRT where I = Interest , P = principal , R = rate , and T = time is used to calculate the amount of simple inter
Irina18 [472]

Answer:

Step-by-step explanation:

I=PRT/100

Multiply both sides by 100

100I=PRT

divide both sides by the coefficient of P which is RT

PRT/RT= 100I/RT

P= 100I/RT
