Question

The square of radius of a circle is X. What is its area?​

Answer 1

Step-by-step explanation:

The area of a circle is pi times the radius squared (A = π r²).

Answer 2

Answer:

Concept:

In geometry, the area contained by a circle of radius r is r2. The Greek letter represents the constant ratio of a circle's circumference to its diameter, which is about 3.14159. Although it is sometimes referred to as the area of a circle in informal contexts, the term disc refers to the circle's interior region, whereas the name circle is reserved for the circle's edge, which is a curve and covers no area. As a result, the area of a disc is a more exact term for the circle's circumference.

Given:

The square of a circle's radius is X.

What is its area?​

Find:

Find the area of the circle.

Answer:

$given$ $data,$

$radius$  $of$ $a$ $circle$  $is$ $x$

$diameter of circle = diagonal of square = 2x cm$

$diameter$ $of$  $circle$  $= diagonal$ $of$ $square$  $= 2x cm$

$area$ $of$ $square$ $=$ $\frac{(diagonal)^2}{2}$

                       $= \frac{(2x)^2}{2}$

                       $= \frac{4x^2}{2}$

                       $= 2x^2 cm$

=> A circle's area is pi times the radius squared (A = r2). Learn how to find the area of a circle given the diameter using this formula. The radius is the distance between the circle's center and its edge. Regardless of how you measure it, the radius will be the same. A circle's radius is also one-half of its diameter. The diameter is the line segment that runs through the center of the circle and joins the opposite sides.
