The radius of a circle is increased by 1%. find how much % does its area increases?

Answer 1

$100 \: \: \: to \: \: 101$
earlier area=π100^2=10000π
now area=101^2π=10201π
increase=201
%=201/10000×100=2.01% increase
hope this helps you

Answer 2

Answer:2.01%

Step-by-step explanation:

earlier area=100^2π=10000π

now area=101^2π=10201π

increase=(now area-earlier area) =(10201-10000) =201

In percentage(%)=201/10000×100=2.01% increase
