Question

FIRST PROPER ANSWER GETS BRAINLIEST ON TEST PLEASE HELP!!!

Answer 1

Area of a semicircle = $\pi$ 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

Answer 2

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$(A= \pi r^2)$
Which is $(1/2)* (\pi r^2)$
So plug in 2.5 for r, which is half of the diameter of 5
You should have this equation: $A=3.14*2.5^2$
Which is equal to: $A=19.625$
Lastly you divide that by 2: $19.625/2=9.8125$
Final Answer: $A=9.81$
