[Solved] Write a code to calculate the circumference and area of …
WebA = C [set area equal to circumference] πR2 = 2πR [use formulas for area and circumference of a circle] R2 = 2R [divide both sides by π] R2 – 2R = 0. R (R – 2) = 0. So the solutions are R = 2 and R = 0. The first solution, … WebThe area under the receiver operating characteristic curves (AUC) was used to contrast the diagnostic accuracy of screening tools. ... years old. 3 Several studies have revealed that sarcopenia leads to deterioration of activities of daily living, 4 physical function, 5 and increased mortality 6 in geriatric populations.

How to Find the Circumference of a Circle Using Its Area
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! 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. Area of a circle is given by. π r 2 = π × 64 = 201.088 cm 2. Circumference of a circle is given by. 2 π r = 2 × π × 8 = 50.272 cm. Example 2 WebJul 17, 2014 · This simple program uses Scanner to obtain a radius from the user, then calculates and outputs the circumference and area..
