Question

114. दो वृत्तों की परिधियाँ 264 मी. और 352 मी.
है। इन दोनों वृत्तों के क्षेत्रफल में कितना अंतर​

Answer 1

Answer:    difference of area of both circles = $4312$ square meter

Step-by-step explanation:

Alright, lets get started.

The circumference of first circle is : $264 m$

Hence the radius will be : $2\pi r=264$

$r=42$

So the area of first circle will be : $\pi r^2$

Area of first circle = $5544$

The circumference of second circle is : $352 m$

Hence the radius will be : $2\pi r=352$

$r=56$

So the area of second circle will be : $\pi r^2$

Area of second circle = $9856$

So the difference of area of both circles will be : $9856-5544$

difference of area of both circles = $4312$ square meter    :   Answer
