PLZ HELP

a quarter circle has radius of 7 centimeters. What is the area of this figure? Use 3.14 for pi. Round your final answer to the nearest hundredth.

Answer 1

`A=38.47\ cm^(2)`

Explanation:

we know that

The area of a quarter circle is equal to

`A=(1/4)\pi r^(2)`

we have

`r=7\ cm`

substitute the values

`A=(1/4)(3.14)(7)^(2)=38.47\ cm^(2)`
