Answer:
#program in python.
#variables
slice_area=14.125
pi=3.14159
#read diameter
d=int(input("Enter diameter of pizza:"))
#area of pizza
area=pi*(d/2)*(d/2)
#number of slice
no_slice=int(area/slice_area)
#print slice
print("total silce are:",no_slice)
Explanation:
Declare and initialize a variable "slice_area" with 14.125 which is the area of a pizza slice.Initialize a variable "pi" with 3.14159.Then read the diameter of pizza.Find the area of pizza as "area=pi *d/2*d/2".Divide the total area with area of pizza slice.This will be the number of slice.
Output:
Enter diameter of pizza:20
total silce are: 22
Answer:
The given statement is False.
Explanation:
- Needs Met Rating of a result show us that how much the result is fulfilling the query of the user. The greater the needs met rating is, the greater the satisfaction of the user is.
- If a page has high quality then it can or can not be useful for the user.
- If the page has high quality as well as high needs met rating then it is best for the user.
- If the page has high quality and has low needs met rating that means it is not relevant to the query so not useful for the user.
- Thus, it is concluded that high quality pages in a task shouldn't all get the same needs met rating rating rather need met rating is dependent upon the relevancy and usefulness of the result to the need and query of the user.
Answer:
- the Keyboard:
The keyboard is a handheld device used to input alphabet, numbers, symbols and characters to a monitor. It also houses the special manipulative and function keys.
- the Control Unit:
The control unit is a component of the CPU which directs the operation of the processor.
- the Printer:
The printer is an external hardware output device which takes electronic data stored on a device and creates a hard copy.
Because machine (cpu) can only execute machine code(language).
With digital technology, the storage method has changed and today it is much easier to handle and transport movies to theatres than in the past. Servers, hard disks and video tapes are being used to store movies and digital projectors are being used to screen them.
