Question

Find the area of a circle with radius of the 5.58 give your answer rounded to 2DP?? pls help

Answer 1

Area is 97.82.

Explanation:

Area of Circle

`A = \pi r^2`

A ... area of circle

r ... radius

Given

r = 5.58

Now insert radius in formula and use a calculator.

`A = \pi r^2`

`A = \pi (5.58)^2`

`A = \pi (31.1364)`

`A \approx 97.8178855`

Rounded to two decimal places:

`A = 97.82`
