Answer:178.71696m^3

Step-by-step explanation:

To find the volume of cone=1/3πr2h

To find the height using pythagoras theorem and the theorem state that the square on the hypotenuse of a right-angled triangle is the same or equal in area to the sum of the squares on the other two sides.

7^2=h^2+3^2

h^2=49-9

h=√40

h=6.32m

V=1/3×3.142×3m×3m×6.32m

Therefore our answer is;

V=178.71696m^3

Can you help me with this​
MrRa [10]

Answer:

p(x - 4) = x³ - 12x² + 48x - 69

Step-by-step explanation:

To evaluate p(x - 4), substitute a = x - 4 into p(a), that is

p(x - 4) = (x - 4)³ - 5

            = (x - 4)(x - 4)(x - 4) - 5 ← expand 2nd/ 3rd factors using FOIL

            = (x - 4)(x² - 8x + 16) - 5 ← distribute parenthesis

            = x³ - 8x² + 16x - 4x² + 32x - 64 - 5 ← collect like terms

           = x³ - 12x² + 48x - 69

The diameter of the jar of marshmallow fluff is 5in. What is the area of the jar opening? Please show the steps how to do that.
Naddika [18.5K]

The opening of the jar is a circle.

The area of any circle is      (pi) x (radius)²

What's the radius of the jar ?
Well, the diameter is 5 inches.
Radius = 1/2 of the diameter = 2.5 inches.

So     Area = (pi) x (2.5 inches)² =

                   (3.14) x (6.25 square inches) =  <em>19.625 square inches</em>.
