A standard dartboard has a diameter of 18 in. What is its area to the nearest square inch?
Reptile [31]
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= \pi r^{2}, where r is equal to the radius of the circle.

In this exercise is given that the diameter of a standard cardboard is 18 inches or a radius of 9 inches and it is asked to find its area. Therefore, to find the area of the circle you should substitute the value of the radius into the previous mention formula.

A= \pi r^{2}
A= \pi (9 in)^{2}
A= \pi (81 in^{2})
A=254.47 in^{2}

The area of the standard dartboard is 254.47 square inches or 254 square inches.
