The total space in the parking lot is 1600 cars
It is mentioned that
parts of this parking is filled
Now we are required to find what is the three-fourths part of 1600
To find it we multiply
times 1600

= 
=
= 1200 cars
Hence 1200 cars fills the three-fourths of the car parking lot that has a capacity of 1600 cars
Hi,
You just have to change z^25 to z^24 or z^27.

Answer: Area of the shaded region is 6.867 square cm
Step-by-step explanation:
The shaded area corresponds to the difference of the area of the rectangle and the area of the semicircle.
Area of the rectangle = 4 times 8 = 32 cm^2
Area of the semicircle = 0.5 * pi * r^2 (where r is the radius, i.e., half of the diameters, i.e., 4 cm). So Area = 0.5*pi*4^2 = 25.133 cm^2
The difference: 32 - 25.133 = 6.867 cm^2 (area of the shaded region)
A negative plus a positive equals a negative
just realized this is an old question
