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
The correct answer would be D

Answer:
ofstream asia("asiasales2009.txt"); //It is used to open asiasales2009.txt files with the asia objects.
ofstream europe("europesales2009.txt"); //It is used to open europesales2009.txt files with the europe objects.
ofstream africa("africasales2009.txt");
//It is used to open africasales2009.txt files with the africa objects.
ofstream latin("latinamericasales2009.txt");//It is used to open latinamericasales2009.txt files with the latin objects.
Explanation:
- The above code is written in the c++ language which is used to open the specified files with the specified objects by the help of ofstream class as described in the question-statements.
- The ofstream is used to open the file in the c++ programing language, so when a user wants to use the ofstream to open the file in written mode, then he needs to follow the below syntax--
ofstream object("file_name_with_extension");
Answer:
D. Sequence number
Explanation:
The sequence number facilitates the keeping track of many segments. This enables it to determine which segments out of many in which it should be in. The sequence number field is usually 32 bits.
Sequence numbers are used in transmitting data because of their importance. Since data is transmitted in packets, they can be lost and as such the receiver uses the sequence numbers to reorder them.
