Answer:
=293.7m²
Step-by-step explanation:
Area of the shaded region = area of the circle-area of the minor segment.
The area of the minor segment is calculated as follows.
Area= Area of sector - area of the triangle bound by the radii.
=∅/360πr²-1/2r²sin∅, where r is the radius of the circle and ∅ the obtuse angle bound by the radii.
=130/360×π×11.1²-1/2×11.1²sin130
=93.43m²
Area of the whole circle =πr²
=π×11.1²
=387.08m²
Area of the shaded region
=387.08m²-93.43m²
=293.65m²
≅293.7m² to the nearest tenth.
To solve (8/5 + 4)7, you first have to add 8/5+4. But you cannot simply add the too because they have to be in a common denominator 'form'. To do that, we find a common denominator which is 5. We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28. You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1. Another of saying 28/5 is 5 3/5. So 5 3/5 x 7/1= 39 2/10 (final answer)
