What is the area of a semi circle that has a diameter of 1 1/2?
SVEN [57.7K]

Answer:

A=0.8836

Step-by-step explanation:

Area of circle:

\pi r^2

By using the area of a circle, we can get the area of a semicircle:

\frac{\pi r^2}{2}

Let's convert the mixed fraction to an improper fraction and then a decimal:

1\frac{1}{2} = \frac{3}{2} = 1.5

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

\frac{1.5}{2} =0.75

Now we have the radius, so we can plug in our values and find the area:

\frac{\pi0.75^2}{2} = 0.88357293

A=0.88357293
