First proper answer gets brainliest on test !

this semicircle has a diameter of 5 what is the area of this figure? use 3.14 for pi

enter your answer as a decimal in the box round your answer to the nearest hundredth

: )

Area of a semicircle =  r² / 2 
r= 5/2 = 2.5

So: A= 3.14 x 2.5² / 2  A = 9.8125 so rounding to the nearest hundredth is A=9.81

Okay, so first you have to understand this:
Since it's a Semicircle, it's half of a circle.
So take half of the Area of the Circle
Which is 
So plug in 2.5 for r, which is half of the diameter of 5
You should have this equation: 
Which is equal to: 
Lastly you divide that by 2:
