V = 
is the formula to find the volume of a sphere.
First cube the radius (12)
= 1728
Now multiply 1728 by 4/3 by multiplying it by 4, and then dividing the result by 3.
1728 x 4 = 6912
= 2304
Now, we multiply this number by to get our final answer.
You typically use 3.14 to approximate.
2304 x 3.14 = 7234.56
Therefore, the volume of a sphere with a radius of 12 will be approximately 7234.56
Hope this helps!!
Let me know if there's anything you don't understand and I'll try to explain as best I can.

The picture in the attached figure
we know that
<span>In a square pyramid we have five faces, 4 triangles and 1 square. So to determine surface area we need to take the areas of the triangles and square and add them all up

<span>In a square pyramid we have five faces, 4 triangles and 1 square. So to determine surface area we need to take the areas of the triangles and square and add them all up
</span>
The square's area is relatively simple:
A=b²
A=6²=36 ft²
But now let's observe the triangles, a triangle's area is:
<span>A=(<span>1/2)*</span>b*h</span>
the base is equal to 6 ft
b=6 ft
AC=BC----------> because the angle is 45°
AC=6 ft/2----> 3 ft
so
BC=3 ft
A=(1/2)*6*3----> 9 ft²
<span>Multiply the triangle's area by four to account for all four triangular faces and add the squares area for your answer</span>
<span>Surface area=36 +4*9-----> 72 ft</span>²
the answer is
72 ft²
