It is: 1/4*pi*144 = 36*pi square units
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
Just like any other circle, the area of that one is (pi) times (the square of the radius).

To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
A=pi x (radius)2 Ans=pi x (radius)2 x 1/4
A circle with a radius of 21 units has an area of 1,385.44 square units.
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
pi
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.
Just like any other circle, the area of that one is (pi) times (the square of the radius).

the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
A radius squared fits pi times into a circle (The area of a circle divided by pi is the radius squared).
