Answer:
lateral area = 2320 m²
Step-by-step explanation:
The question wants us to calculate the lateral area of a square base pyramid. The square base pyramid has a side of 40 meters.The height is 21 meters.
Half of the square base is 40/2 = 20 meters . With the height it forms a right angle triangle. The hypotenuse side is the slant height of the pyramid.
Using Pythagoras's theorem
c² = a² + b²
c² = 20² + 21²
c² = 400 + 441
c² = 841
square root both sides
c = √841
c = 29 meters
The slant height of the pyramid is 29 meters.
The pyramid has four sided triangle. The lateral area is 4 multiply by the area of one triangle.
area of triangle = 1/2 × base × height
base = 40 meters
height = 29 meters
area = 1/2 × 40 × 29
area = 580
area of one triangle = 580 m²
Lateral area = 4(580)
lateral area = 2320 m²
After graphing the lines, you can see that the solution is (4, -1)
Yes if u can multiply 10 by 1000 then it is a multiplication fact
Year 3 = 2s
Year 2 = 3 + x
Year 1 = x
s = second year
x = first year
2s = 26
s = 13
The second year they made 13 million
13 - 3 = 10
x = 10
They made 10 million the first year.
<span>(Y+2) at y=-4
First: You will plug in your y
Your equation should look like: -4+2
Next: You will take 2 and subtract the 4
You will get: -2 as your answer
HOPE THIS HELPS! ^_^</span>
