Answer:
The circumference of the round pizza is 21.26in
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 36in²
r = radius
π = 3.14
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(36in²/3.14)
r = √(11.46in²)
r = 3.385 in
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = 3.14 * 2 * 3.385 in
c = 21.26in
The circumference of the circle is 21.26in
Answer:
Step-by-step explanation:
Let X be the mean height of peak patrons,
Then X is normal with mean = 68 inches and std dev = 12 inches
Whenever x<54, they are not allowed to use the ride.
x=54 means z=
The z for 54" is 
From std normal table we find that the area to the left of -1.17 is
0.3790
P(X>54) =1-0.3790
=0.6210=62.10%
P(54<x<68) = 0.5-0.3790 =0.121=12.1%
P(X>68) =0.5%=50%
3.55 x 4
thats the amount per bag times the number of bags you buy.
use a calculator and you get $14.20
