r = 15 cm
Explanation:formula
V = πr²×h/3
replace
4950 = 22/7×r²×21/3
4950 = 22/7×r²×7
4950 = 22×r²
r² = 4950/22
r² = 225
r = √225
r = √15²
r = 15 cm

We have written a method called sum with an int[] parameter nums. We want our sum method to compute the sum of nums, but our code has a bug (or perhaps bugs?) in it.
Fix the bugs.
Answer:
Following are the code to this question:
public class Main//defining a class-main
{
public static int sum(int[] nums)//defining a method sum that accepts array
{
int total = 0;//defining integer variable total
for(int num : nums) // use for-each loop
{
total += num;//add array value in total variable
}
return total;//use return keyword to return the total value
}
public static void main(String []ar )//defining a main method
{
int[] nums={1,2,3,4,5};//defining 1-D array nums
System.out.println(sum(nums));//use print function to call sum method
}
}
Output:
15
Explanation:
In the class "Main", a static method, "sum" is defined, that accepts array in its parameter and inside the method, an integer variable "total" is define, that uses the for each loop to add array value in a total variable and use a return keyword to return its value.
Inside the main method, an integer array nums are defined, that holds store some values and use the print function to call the sum method.

(BRAINLIEST QUESTION) What are some challenges that will need to be overcome in order for the Internet of Vehicles to become a reality?
Answer:
Internet of Vehicles (IoV) is a concept in intelligent transportation systems (ITS) in which vehicles with IoV will be able to communicate with each other and [ublic networks through V2I (vehicle-to-infrastructure), V2P (vehicle-to-pedestrian) interaction, and V2V (vehicle-to-vehicle).
There are some challenges that will need to be overcome in order for the Internet of Vehicles to become a reality:
IoV is unable to predict human behavior and body language of other drivers so it can be dangerous sometimes to take respective actions that a normal vehicle driver can do. Risk of security challenges and security attacks is one of the biggest challenges as the networks can be manipulated.People have lack of trust in IoV due to privacy and health concern.The initial cost of IoV is very high that only few rich people can buy it.Conversion Practice: Find the equivalent binary or decimal numbers below.
