The meaning of the area is the measurement of a surface in this case a circle, which can be find by using the formula A=πr^2, where r is equal to the radius of the circle.
On this exercise is given that the radius of the circle is 9 cm and it is asked to find its area and use 3.14 as the value of π. Therefore, to find the area of the circle you should substitute the value of the radius and the value of pi into the formula A=πr^2.
A=πr^2
A=(3.14)(9)^2
A=(3.14)(81)
A=254.34
The area of the circle is 254.34 cubic centimeters.
