Question

Area of a rectangle and the area of a circle are equal . if the dimensions of the rectangle are 14cm×11cm , then radius of the circle is

Answer 1

14×11 =πr^2
: r^2=7×7
:r=7 cm

Answer 2

length of rectangle equals to 14 cm
breadth of rectangle equal to 11 cm
therefore area of rectangle equal to 154 cm square
since area of rectangle equal to area of circle
therefore , π× r × r = 154
r×r=49
r=7
