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>
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
Answer:
3 is the gradient.
Step-by-step explanation:
take coordinates through which the line is passing through like
( 0 , -2 ) and ( 6 , 16 )
to find slope/ gradient = ( y2 - y1 )/ ( x2 -x1 )
= ( 16 - -2 ) / ( 6 - 0 )
= 3
to confirm, let me find the equation as well:
y - 16 = 3 ( x - 6 )
y - 16 = 3x - 18
y = 3x - 2
below for visual check. its true and matches. { confirmed }
