The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)

Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So, 
So, we can apply normal approximation.
Mean = 20
Standard deviation = 
Since 
So, Probability that fewer than 30 but a packet after testing a free sample is given by

Hence, our required probability is 0.99338.
Answer:
Katy is 6 cm taller.
Step-by-step explanation:
Katy: 1 meter=100cm
100cm+18cm=118cm
Beth: 112cm
