V = (1/3)pi*r^2*h that's the formula to used to get the volume of the cone
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)

X= 4y+4/3yz this is they solution
We know that the perimeter of a rectangle is 2(width)+2(length). We can multiply the length by 2 to find out how much remaining fencing we have, then divide that number by 2 to find the width.
15.5*2=31
170.5-31=139.5
139.5/2=69.75
A possible width is 69.75 feet.
Answer:
1. b < -2 or b > 2
Step-by-step explanation:
|b| > 2
you get 2 solutions, one positive and one negative
remember to flip the inequality for the negative
b>2 or b<-2
