Answer 1

Answer:

10.8 m²

Step-by-step explanation:

To find area, we do 3.14*r^2

since diameter = 2 radius divide each by 2

2 and 0.75

A outer= 3.14*2^2

3.14*4

12.56 m²

A inner = 3.14*0.75^2

≈1.8 m²

to find the shaded area subtract the outer from the inner

12.56-1.8=10.76

which rounds up to

10.8 m²

If we use π then we get

about

12.57

and

1.77

subtract to get

10.8 m²
