Answer 1

Answer:

ok

Step-by-step explanation:

Answer 2

Answer: Step-by-step explanation:

Four small circle having radius=r

bigger circles radius is=R

Circumference of circle is =2×π×r

4×2πr=2πR

R=4r

Area=area of bigger circle/area of small circle

Area=π×R×R/π×r×r

Area=(R/r)^2(put value of R in given )

=4×4

=16
