Answer: See below

Step-by-step explanation:

The formula for volume is V= πr^2h

Plug in the values

5.5 ft / 2 = 2.75 ft

and h = height which is 8ft

So, V= (3.14)(2.75ft)^2(8ft) = answer!

Hope this helps! :)

Answer:

∠AEB = 72°

Step-by-step explanation:

Finding x

∠AEB = ∠DEC (Vertically opposite angles)
7x - 5 = 2(4x - 8)
7x - 5 = 8x - 16
8x - 7x = -5 + 16
x = 11

Finding ∠AEB

7x - 5
7(11) - 5
77 - 5
∠AEB = 72°

The pyramid shown has a square base that is 12 inches on each side. It has a surface area of 336 square inches. What is the slan

blagie [28]

Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh

Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24

The slant height is 8 inches.
