SA of a pyramid: 1/2ph + B
p = perimeter of base
h = slant height
B = area of base
Perimeter of base:
The pyramid has a square base, so take a side of the base and multiply it by 4 sides to find the perimeter of the base.
(2)(4) = 8 cm
Slant height:
The diagram shows that the slant height of the pyramid is 4 cm.
Area of base:
Since the pyramid has a square base, square one side of the base to find the area of the pyramid.
2cm² = 4 cm²
Now plug in the perimeter, slant height, and area of the base into the formula for SA of a pyramid.
1/2(8)(4) + 4
16 + 4 = 20 cm²
The surface area of the pyramid is 20 cm².
What function can you post it please and thank you
i would subtract 7 and divide by 4;
4x + 7 = 15
4x = 8
x = 2
ANSWER
EXPLANATION
The given angle is 870°.
870°-360°-360°=150°
This means that:
870° is coterminal with 150°, hence its terminal side is in the second quadrant.
It makes an acute angle of 30° with the x-axis.
Note that cotangent is negative in the second quadrant,
Hence,
The first option is correct.
Answer:
y=-3/11x+67/11
Step-by-step explanation:
y-8=-5-8/4--7(x--7)
y-8=-3/11(x+7)
11y-88=-3x-21
11y=-3x-21+88
11y=-3x+67
y=-3/11x+67/11
