Question

Area of a rectangle and the area of a circle are equal. If the dimensions of the rectangle are 14cm × 11 cm. Find the radius of the circle .

Answer 1

7cm

Explanation:

Area of rectangle: length × breadth

14cm × 11cm= 154cm²

Area of a circle:
`\pi\\`r²

`(22)/(7)` × r × r= 154cm²

`(22)/(7)` x r²= 154cm²

r²= 154 x
`(7)/(22)`

r²= 49

r= √49

r= 7
