The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.
Because the 2 sides are the same the 2 bottom angles are also the same.
This means that 9x +3 = 84
Now we can solve for x:
9x +3 = 84
Subtract 3 from each side:
9x = 91
Divide both sides by 9:
x = 81 / 9
x = 9
this equals = 3 4/40 =☆ 3 1/10☆
Answer:
B) 49,062.5 ft²
Step-by-step explanation:
The area of a circle can be found using the following equation:
A(c) = πr²
Note:
A(c) = Area of circle
π = pi = 3.14
r = radius
The diameter of the circle is given to you. To find the radius, simply divide the diameter by 2:
Diameter/2 = Radius
Radius = 250/2 = 125
Next, plug in 125 into the Area formula for circle for r:
A(c) = πr²
A(c) = π(125)²
A(c) = π * 15625
A(c) = 3.14 * 15625
A(c) ≈ 49062.5
B) 49,062.5 ft² is your answer.
