Question

Radius of the circle is 1m.If its diameter is increased by 100% its area is increased by

Answer 1

Answer

Let the diameter be 100 cm.

Let the diameter be 100 cm.New diameter = 200 cm

Let the diameter be 100 cm.New diameter = 200 cmChange in area = π(100)^2−π(50)^2

2=π(100+50)(100−50)

2=π(100+50)(100−50)=π×150×50

2=π(100+50)(100−50)=π×150×50= 7500π cm^2.

2.Percentage increase = 7500ππ×50×50×100 = 300%

Let the diameter be 100 cm.

New diameter = 200 cm

Change in area = π(100)^2−π(50)^2

=π(100+50)(100−50)

=π×150×50

= 7500πcm^2.

Percentage increase = 7500ππ×50×50×100 = 300%
