What happens to the area of a circle when the diameter is halved?

Answer 1

When the diameter of a circle is halved, the radius is also halved since the radius is half of the diameter. The area of a circle is calculated using the formula A = πr^2, where r is the radius. If the radius is halved, the area is reduced to one-fourth of its original size because the radius is squared in the formula. Therefore, halving the diameter of a circle results in the area being reduced to one-fourth of its original area.

Answer 2

Oh, dude, when you halve the diameter of a circle, the radius is also halved because they're like best buds or something. So, the area of the circle doesn't just get cut in half, it actually gets reduced to one-fourth of its original size. It's like shrinking a Pizza, but not as tasty.

Answer 3

It is reduced by a quarter.

If you halve the you also halve the diameter

The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.
