perimeter should be 43 and the area should be 72m^2
this is squared btw
Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
Answer:
Parallel segments → 1
perpendicular segments → 2
congruent segments → 3
hope it helps...
have a great day!!
