3 days ago · Answer. Verified. 441k + views. Hint: Pi (π) is the ratio of the circumference of a circle to its diameter. It doesn't matter how big or small the circle is - the ratio stays the same. Properties like this that stay the same when you change other attributes are called constants. Complete step-by-step answer: In Geometry, for computing the area ...
5 days ago · The formula for the area of a circle, \(A = \pi r^2\), is a fundamental concept in geometry that applies to pizzas as well since they are typically circular. Pizza Area Formula. The pizza area formula is a specific application of the circle area formula, tailored for pizzas: \[ PA = \pi \left(\frac{PD}{2}\right)^2 \] where: \(PA\) is the Pizza ...

5 days ago · Then we just need to use the area formula of squares to get the required answer. Complete step-by-step answer: Given radius of the circle. = x cm = x cm. We know that diameter of the circle is equal to double of the radius of the circle. Diameter of the circle. d = 2r = 2(x) = 2x cm d = 2 r = 2 ( x) = 2 x cm.
3 days ago · Over centuries, mathematicians developed formulas to calculate areas of more complex shapes, including segments of circles. Calculation Formula. The area of a corner or segment of a circle can be calculated using the formula: \[ S = (1 - \frac {\pi}{4})r^2 \] where: \(S\) is the area of the corner, \(r\) is the radius of the circle. Example ...
