the area and circumfrence of a circle are numerically equal . what is the radius of circle\xa0 |
| Answer» Ans. Let Radius of Circle = r\xa0Then Circumference of Circle =\xa0{tex}2\\pi r{/tex}Area of Circle =\xa0{tex}\\pi r^2{/tex}According to Ques.{tex}=> 2\\pi r = \\pi r^2 {/tex}{tex}=> r = 2{/tex}So Radius of circle = 2 unit | |
