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 setdistance 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.

Twenty four(24) minus 1/3

Answers

23 and 2/3
you have 24 and you are taking away 1/3 of a whole
1/3 is equal to .333333333 repeating, as a decimal
therefore 1/3 is less than 1
you are taking away 1/3 of 1 away from 24
1 is equal to 3/3
take away 1/3 and you are left with 2/3
3/3-1/3=2/3
2/3 + 23 (the number that you did not touch)
and you are left with 23 2/3
