Answer» Radius of the THIRD circle will be 24 METRES. Step-by-step EXPLANATION: Step 1 : FIND the area of first circle : Here, radius will be 7metres. (given)Area of a circle is given by : πr² ‘r’ is the radius So, → π × 7² → π*49→ 49πStep 2 : Find the area of the second circle : Radius will be taken as 25metres. (given) Area of the circle : πr²→ π × 25²→ 625π Step 3 : Find the radius of the third circle : Given : Area of the third circle : Area of the second circle - Area of the first circle So, Area of the third circle = 625π - 49π→ πr² = 576π→ r² = 576→ r = √576→ r = 24metres.Radius of the third circle will be 24 metres. |
