Answer:
78.55m^2
Step-by-step explanation:
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
A = 25pi or approximately 78.5 m^2
The area of a circle is given by
A = pi r^2
A = pi 5^2
A = 25 pi
We can approximate pi by 3.14
A = 25*3.14
A is approximately 78.5
