- 3. Given the following variables and their values: Sagot = true A = 2 B= 4 Letter = ‘c’ Pi = 3.14Requirements:a) Write a Java program that prints the values of the variables above in this manner The value of A is 2 while B is 4 Letter c Initial value of Sagot is true Pi contains the value 3.14 Sagot is now false** for the last line of output, determine if A is greater than Bb) Display the product of A and B without declaring another variable. Display the result in this manner : 2 * 4 = 8Assume that a runner runs 15 kilometers in 50 minutes and 30 seconds. Write a Java program that displays the average speed in miles per hour. (Note that 1 mile is 1.6 kilometers.). Note: You have to replace the question mark with the correct answer.Use Java ⮚ Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M. ⮚ Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000.⮚ For example, 2 is written as II in Roman numeral, just two ones added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II. ⮚ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. X can be placed before L (50) and C (100) to make 40 and 90. C can be placed before D (500) and M (1000) to make 400 and 900. ⮚ Given a roman numeral, convert it to an integer

The initial value of the radius of a circle is equal to one unit and each succeeding radius is one unit greater than the value before it. Build a program to compute the area of the circle starting with R=1.0 up to R=5.0, then print out each radius and the corresponding area of the circle. USED JAVA PROGRAMMINGCode the following statments in JAVA If your average time to run each mile is under 11 minutes, display a"you got gold" message 5. If your average time to run each mile is under 15 minutes, display a"you got silver" message 6. If your average time to run each mile is equal to or more than 15minutes, "you got bronze" message
