What is the slant height of a square pyramid that has a surface area of 319 square feet and a side length of 11 feet?

Dafna1 [17]

Step-by-step explanation:

Surface area of a square pyramid is the area of the square base plus the area of the four triangles made from the base and the slant height.

SA = s² + 4(sh/2)

which reduces to:

SA = s² + 2sh

You are told that s = 11 and SA = 319. You can now solve for h:

319 = 11² + 2(11)h

319 = 121 + 22h

198 = 22h

h = 9 ft (answer C)

I hope it's helpful!!

ivann1987 [24]

Answer:

Step-by-step explanation:

Total length of the fabric is $6\dfrac{2}{3}=\dfrac{20}{3}\ \text{yards}$

We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.

Let she needs x scarves. So, ATQ

$x\times \dfrac{5}{6}=\dfrac{20}{3}\\\\x=\dfrac{20}{3}\cdot\dfrac{6}{5}\\\\x=8$

Hence, she can make 8 scarves.
