Answer:
(-2.4, -1)
Step-by-step explanation:
When you mirror a point across the y-axis, which is the vertical axis, the x-coordinate changes it's sign from either positive to negative or negative to positive.
(-2.4,-1)
78.55m^2
General formula for the area of a circle is πr^2
π=3.12
r=5m
So let's apply the formula
3.142×(5)^2
3.142×25
78.55
So the area is 78.55m^2
it should be 64 ....
