Answer 2

Step-by-step explanation:

1 :

radii of the first circle = 6cm = r1

radii of the second circle = 4cm = r 2

area of first circle = pi ×r1 ^2

= 3.14 × 6× 6

=113.04cm^2

area of second circle = pi ×r2^ 2

= 3.14 ×4×4

= 50.24cm ^2

shaded region =113.04- 50.24

= 62.80cm ^2 it is the answar

2 answar:::::::

area of bigger circle is = 164 pi cm^2

area of smallest circle is = 61 pi cm ^2

find redius

formula for biggest circle

= Pi ×R 1^2 = 164 pi cm ^ 2

pi cut from both side

R1 = √ 164 = 12.806248 cm
