Answer:
25.15cm² which means option B 25.13
Because I used 22/7 for pi instead of 3.14
Step-by-step explanation:
radius of the small circle = 2 cm
diameter = 2 x 2 cm = 4cm
this is the radius for the big circle.
Area of big circle = pi × r²
= 22/7 x 4²
= 22/7 x 16
= 50.29cm²
Now area of small circle = pi x small radius²
= 22/7 x 2²
= 22/7 x 4
= 12.57
Now,
The area of shaded region = area of big circle - 2 x small circles
= 50.29 - 2 x 12.57
= 50.29 - 25.14
= 25.15cm²
