Question

Pls help me in this question.

Answer 1

Answer:

are of shaded region=π(R^2-r^2)

22/7(100-36)

22/7×64

201.088

Step-by-step explanation:

if my calculations are correct then this is the answer

Answer 2

Step-by-step explanation:

LET BIG RADIOUS (R)=10 CM

LET SMALL RADIOUS (r)=6 CM

AREA OF BIG CIRCLE =π×R^2

AREA OF BIG CIRCLE=π×100=100π CM^2

AREA OF SMALL CIRCLE=π×r^2

AREA OF SMALL CIRCLE=π×36=36π

CM^2

AREA OF SHADED REGION

=AREA OF BIG CIRCLE -AREA OF SMALL CIRCLE

=100π-36π=64π CM^2
