Answer: When I pressed the answer it honestly didn't give me no right or wrong answer. So you can choose all of them and you won't get them wrong lol:)
8.54 x 10^3 =
8.54 x 1,000 =
8,540
The first bullet is correct.
Answer: ~54.54 units squared, or 25*pi - 24
Step-by-step explanation:
To find this, we need to find both the area of the triangle and circle, and then subtract the area of the triangle from the area of the circle.
Area of triangle:
Area of circle:
To find the radius, we first need to find the hypotenuse of the triangle, which happens to be the diameter of the circle.
Pythagorean Theorem: , where a and b are sides and c is the hypotenuse.
6^2 + 8^2 = c^2
36 + 64 = 100, c = 10
Knowing that the diameter is 10, we also know that the radius is 5.
Area of the circle with a radius of 5 is 25*pi, or 78.54~
Area of the triangle with side lengths of 6 and 8 is 24.
78.54 - 24 = 54.54 units squared.
The answer is x+4 - 1/x+4
Hope that helps you.
