Question

What is the area of a circle that has a radius of 5 meters

Answer 1

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

Answer 2

Answer:

A = 25pi or approximately 78.5 m^2

Step-by-step explanation:

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
