Question

Calculate the area of a circle that has a diameter of 5 meters. Use 3.14 forpi. Round your answer to the nearest hundredth. *

Answer 1

The area of a circle can be calculated with the equation:

`\text{area}=\pi\cdot r^2`

the radius (r) is the diameter/2 so

r=5/2=2.5

and

π=3.14

`3.14\cdot(2.5)^2=19.625`

but they ask you to round it to the nearest hundredth, which means 2 numbers after the point, so the answer is:

area of the circle: 19.63
