Answer 1

hey mate here is what u want

hope it helps u

Answer 2

Answer:

Answer is Option C 75%

Step-by-step explanation:

New radius=50%, R=R/2

original area =πR^2

New area = π(R/2)^2

= πR^2/4

therefore ,

Required d%= πR^2-πR^2

_____________ ×100

πR^2

= 3/4 × πr^2 / πr^2 ×100

= 25×3=75

=75%

Hope it helps you my friend
