Circumference as a function of area
WebOct 1, 2015 · Explanation: So the radius is r = P 2π. And since the area is A = πr2. We can rewrite this as: A = π( P 2π)2 = π ⋅ ( P 2 4 ⋅ π⋅ π) = P 2 4π. Answer link. WebTherefore, the Area is (pi)r^2 A = (pi)0.25*0.25 = 0.0625(pi) There is no rule that if Radius or Diameter is a decimal, then the Area and the Circumference is also decimal but it ALMOST always shows up that way. Even if it is a decimal no difference. You just have to be careful with all those decimal points!

WebApr 14, 2024 · In this example code, we create two instances of the "Book" class and add them to the collection with the ‘addBook’ method. We then print the title, author, and ISBN of each book in the collection using a for loop. We also remove book1 from the collection using the ‘removeBook’ method and print the updated collection. Sample Output: WebArea of a circle, A = πr 2 square units. Circumference / Perimeter = 2πr units. Area of a circle can be calculated by using the formulas: Area = π × r 2, where 'r' is the radius. Area = (π/4) × d 2, where 'd' is the diameter. Area = C 2 /4π, where 'C' is the circumference (sometimes referred to as perimeter).
WebYou print the area but not the circumference. Your function does not return either the area or the circumference (let alone both), so you're answering a different problem from the … WebSep 30, 2010 · Your code silently loses precision in the statements as there is a implicit double to float standard conversion that applies behind your back: circumference = 2 * 3.1416 * radius; (since 3.1416 is of type double, the type of rhs is double). area = 3.1416 * radius * radius; (same here) So, you lose precison.
WebThe Cal_area() function also takes the radius as input, calculates the area of the circle using the formula 3.14159 * radius * radius, and then displays the result. In the main() function, the program prompts the user to enter the radius value. The entered value is then passed as an argument to the Cal_circumference() and Cal_area() functions ... WebA circle has a radius 8 cm. Calculate its diameter, area and circumference. Solution. Given parameters are, Radius, r = 8cm. Diameter of a circle is given by. 2r = 2 × 8 cm = 16 cm.
