Question

26. Consider two concentric circles. The radius
of the big circle is 10 m and the radius small circle is 5m .find the area​

Answer 1

Answer:

Consider two concentric circles. The radius of the big circle is 42 cm and the radius of the small circle is 35 m. Find the area between the circles.

Step-by-step explanation:

Answer 2

radius of the big circle= R = 10

and for the small = r =5

hence, area of the first circle,

πR^2

= π[10]^2

=100π

and area of the small one,

25π

then the area of concentric circle must be,

100π - 25π

= 75π

= 75 *22/7

= 235.714 (ans)
