I think it’s C but I’m not too sure
The opposite operation of squaring is to find the square root. I dunno what the original equation is so I can’t help with that
We know that
area of the circle=pi*r²
if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units
the answer is
the radius is 6.46 units
Answer:
1,980 would be the area and the perimeter would be 39 im pretty sure
