Question

Find the area of a circle with radius r of 2.5 inches. Round your answer off to one decimal point.

Answer 1

Area of circle= pi (3.14) times by radius (half of diameter) squared So: 19.6 cm squared

Answer 2

For this case, we have that by definition, the area of a circle is given by:

`A = \pi * r ^ 2`

Where:

A: It is the circle radius

In this case,
`r = 2.5` inches

So:

`A = \pi * (2.5) ^ 2\\A = \pi * 6.25\\A = 19.6350`

So, the area of the circle is:

19.6 square inches

Answer:

`19.6 \ in ^ 2`
