Answer :
[tex]d =240 \ mm = 24 \ cm \\\\r = \frac{d}{2} =\frac{24}{2}=12 \ cm \\ \\ \pi=3,14 \\ \\A = \pi r^2\\\\A= 3,14\cdot 12^2 =3,14 \cdot 144 = 452,16 \ cm^2[/tex]
A circle is a curve sketched out by a point moving in a plane. The area of the circle with a diameter of 240 mm is 45238.934 mm².
What is a circle?
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The area of the circle with a diameter of 240 mm is,
Area of circle = (π/4) × D²
= (π/4) × (240)²
= 45238.934 mm²
Hence, the area of the circle with a diameter of 240 mm is 45238.934 mm².
