Find the area of a circle with a radius of 2.5 inches. round to the nearest tenth. use 3.14 for pi.

a=19.6 inches^2

Step-by-step explanation:

The area of a circle can be found using

a=πr^2

We know the radius is 2.5, so we can substitute it in for r

We can also substitute 3.14 in for π

a=(3.14)*(2.5^2)

a=(3.14)*(6.25)

a=19.625

Round to the nearest tenth

a=19.6 inches^2

here the number -5 is all of the following except a rational number.
