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

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
