Answer and Step-by-step explanation:

Since we know that this figure is a square pyramid, the base is a square. And the area of a square is its side multiplied by its side, which the sides would equal the same (since it is a square).

So, we square 625 to find One side of the square.

$\sqrt{625} = 25$

We get 25 as the side.

The volume equation for a square pyramid is:

$V = a^{2}( \frac{h}{3} )$

Where a is the side length of the base, and h is the height.

Plug in the values.

$V = (25)^{2} (\frac{30}{3} )\\\\V = 625(10)\\\\V = 6250$

The volume of the square pyramid is 6250 cubic meters.

Helen wants to find the surface area of the solid pictured on the left, so she constructs a net of the solid pictured on the rig

lana [24]

Answer:

Helen’s net is correct because she reorganized the solid as a triangular prism.

This is because the net has a rectangular base and 4 triangular sides.

Step-by-step explanation:

Rectangular SA one side+1 = 30 x 9 = 270 + 1s= 270 x 2 =540sq^2

Rectangular side one side +1 = 18 x 9 = 162 +1s = 162 x 2 = 324sq^2

2 x 2 triangular sides either end = 4/3 x 15 x 27.3 + 18 x 30.9 = 409.5 (x2) = 819sq^2

=864 + 360

Pyramid area = 1236.71sq^2

Volume = V=1620^3

Use the information given to enter an equation in standard form.

Greeley [361]

Answer:

y = -2x + 25

Step-by-step explanation:

A standard equation can be in slope-intercept form: y = mx + b

m is the slope, b is the y-intercept.

Plug in the given slope.

y = -2x + b

To find b, plug in the given point (9, 7).

7 = -2(9) + b

Multiply.

7 = -18 + b

Add 18 to both sides to find b.

25 = b

Plug this into your standard equation.

y = -2x + 25

Check by plugging in the given point again.

7 = -2(9) + 25

7 = -18 + 25

7 = 7

Your answer is correct!

Hope this helps!

Answer:

138, 460 m²

Step-by-step explanation:

How To Find Volume of Pyramid With Slant Height? If 'x' is the base length, 's' is the slant height, and 'h' is the height of a regular pyramid, then they satisfy the equation (the Pythagoras theorem) (x/2)2 + h2 = s2.
