Find the area of the shaded region.

A) 21.5 m2

B) 25.8 m2

C) 48.2 m2

D) 100 m2

E) 78.5 m2

A

Area of shaded region = 21.5 m^2

Attached is the image used in the question.

Step-by-step explanation:

The area of a square or rectangle is given as;

Area = length × breadth

A = l×b

The area of a circle is;

Area = πr^2 = (πd^2)/4

Given;

From the attached image;

Length l = breadth b = diameter d = 10 m

Area of shaded region = area of square - area of circle

As = l×b - (πd^2)/4

Substituting the values;

As = 10×10 - (π×10^2)/4

As = 100 - 78.54

As = 21.460

As = 21.5 m^2

Area of shaded region = 21.5 m^2

here is your mark brainliest

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
