Question

Area of small circle is 13 metre square..
what is the area of shaded region​

Answer 1

Answer:

Step-by-step explanation:

R of small circle = 13 m

d = 13*2

  = 26m

r of big circle  =  26 m

area of big circle = 22/7 * 26*26

                       = 2124.57 m square.

area of small circle = 22/7*13*13

                                 =  531.14 m square

area of shaded region = 2124.57 - 531.14 m square

                                = 1593.43 m square

Answer 2

Answer:

Area of circle = πr^2

1300=22/7 ×r^2

r^2 =1300×7/22

= 9100/22

=413.6 cm

•: Area of larger =πr^2

=22/7×(8.272)^2

=22/7 × 68.42

= 22×9.77

=214.96
