2π
Step-by-step explanation:
Area = πr^2
= π2^2
= 4π
4π is the area of the whole circle, so divide it in half to get the semicircle.
<u>= 2π</u>

Q2-422
Step-by-step explanation:
Answer:
<em><u>The answer is 4 </u></em><em><u> </u></em><em><u>because </u></em><em><u>the</u></em><em><u> </u></em><em><u>2</u></em><em><u> </u></em><em><u>over</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>canceled</u></em><em><u> </u></em><em><u>out</u></em><em><u /></em>
A= 20x25 so the area is 500
To find the perimeter you have to add both the width and length x2 so it’s 20+25 =45
45x2=90
answer:
B. 2:6 is equal to 1:3
2 and 6 are both even so you can split both of them in half and you would get 1 and 3
