Answer:
106.81
Step-by-step explanation:
first convert diameter to radius
- radius = diameter / 2
- radius = 34/2 = 17
now find circumference
- circumference = 2πr
- circumference = 2π(17) = 106.81
r = radius
if we were to round to the nearest thousand you would get 4,7000
First, find the height of the pyramid using the volume formula.
Then use the Pythagorean theorem to find the slant height.
V = (1/3)Ah
48 = (1/3)(6^2)h
144 = 36h
h = 4
Since the side of the base is 6 in., half the side is 3 in.
The height of the pyramid is 4 in.
Call the slant height S.
3^2 + 4^2 = S^2
9 + 16 = S^2
25 = S^2
S = 5
Answer: The slant height is 5 in.
Z = 114 + 2p
p = 46
Plug in 46 for 'p' in the first equation.
z = 114 + 2p
z = 114 + 2(46)
Multiply:
z = 114 + 92
Add:
z = 206
So the Zigzag river is 206 miles long.
