What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent

Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches

Heeeeeelllllllppppppp

EleoNora [17]

Answer:

Step-by-step explanation:

-7k = 0

Divide both sides by (-7)

k = 0

17) c - 4 = -23

Add 4 to both sides

c - 4 + 4 = -23 + 4

c = - 19

$18) \dfrac{r}{-2}=-16\\\\\\Multiply \ both \ sides \ by \ (-2)\\\\\dfrac{r}{-2}*(-2) = (-16)*(-2)\\\\\\r = 32$
