Question

3. Which has a greater area, a circle with
diameter 3.5 m or a rectangle with sides
8.5 m and 6.5 m? By how much is one area
greater than the other?​

Answer 1

$\large \tt \purple {answer}$

Area of the circle = 2πr = 2x(22/7)xr

= 2 x (22/7) x (3.5/2) = 11 m^2

Area of the rectangle = lb = 8.5 x 6.5 = 55.25 m^2.

So, the area of RECTANGLE isGREATER.

To find by how much is one area greater than the other, we have to divide the greater area by smaller area.

=> 55.25/11 = 5.022727
