Hence using d = 2 (radius) = 2(16) = 32 meters from the question gives us the area as dhcm anchorage
What is the area of a circle with diameter 1.5 m?
WebNov 7, 2024 · 4. Find the radius from the surface area. Use the formula r = √ (A/ (4π)). The surface area of a sphere is derived from the equation A = 4πr 2. Solving for the r variable yields √ (A/ (4π)) = r, meaning that the radius of a sphere is equal to the square root of the surface area divided by 4π. WebAug 2, 2024 · For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. If you only know the area of the circle, use the formula diameter = 2 x √(area/π). So, if the area of the circle is 25 square centimeters, the diameter would be 2 x √(25/π), or approximately 5.64 centimeters. WebThis tool helps to estimate precisely the surface area of the pipe using the formula finding the area of the cylinder: V = π × d × L, where d – is the outer diameter of the pipe … ciftis 2020
