WebL = 2 π rh. Calculate the top and bottom surface area of a cylinder (2 circles ): T = B = π r 2. Total surface area of a closed cylinder is: A = L + T + B = 2 π rh + 2 ( π r 2) = 2 π r (h+r) ** The area calculated is only the lateral surface of the outer cylinder wall. To calculate the total surface area you will need to also calculate the ... WebThe radius is the distance from the edge of the circle to the centre. The diameter is twice as long as the radius. Example. The pizza has a radius of 16 cm. What is the diameter? …

3 Ways to Calculate the Circumference of a Circle - wikiHow

WebDec 15, 2024 · To calculate the circumference of a circle, use the formula C= pi*D where C is the circumference, D is the diameter and pi is 3.14. If you have the radius instead of the diameter, multiply it by two to get the diameter. You can also use the formula for the circumference of a circle using the radius which is C equals 2 pi R where R is the radius. Webprograming in c# Write a program that inputs the radius of a circle as an integer and displays the diameter, circumference, and area using the double 3.14159 for PI. You can use Math.PI as well. The following are how these should be calculated: diameter = 2r circumference = 2πr area = πr^2. C++ for Engineers and Scientists. WebDec 14, 2024 · This is the circle's diameter, in this case, 31.8 centimeters. Divide by 2. This result is the circle's radius of 15.9 centimeters. Multiply the radius with itself, getting the square, in our case 256 cm². Multiply by π, … fokozatos angolul
