Question

Two circular peices of equal radii and maximum area touching each other cut out from a rec. Card of dimension 14 x 7 find remaining area of card board

Answer 1

So, if both the circular pieces have equal radii and maximum area then, the length of rectangle would be equalt to both radii, so 2 radii= 7 and 1 radii= 7 /2 = 3.5

now lets get their area

$2*\pi*7$

that means 2*22/7*7 =  44 so thats the combined area of both circles

now area of rectangle = L* B = 14 * 7 = 98

so subtract area of circles with rectangle, 98 - 44 = 54 which is the answer
