Answer 1

Answer:

first solve the area of the two circles and then subtract the areas of both the circle

Answer 2

Answer:

63²

Step-by-step explanation:

area between the concentric circles = pi (R²-r²)

= 22/7 × (5²cm-2²cm)

=22/7 × (25-4) cm

= 22/7× 21 cm

= 7 cancels 1 time and 22 3 times

= 21 × 3

=63² cm
