Answer:
67.5 units²
Step-by-step explanation:
We can break this problem down in two parts: The upper triangle and the lower trapezoid.
The upper triangle:
Use the formula to compute the area of the triangle. Base = 10 and Height = 7.
1/2 (10)(7)
1/2 (70)
=35 units².
The lower trapezoid:
Use the formula to compute the area of the trapezoid. Base 1 = 10, Base 2 = 3 and Height = 5.
1/2 (10 + 3)(5)
1/2 (13)(5)
1/2 (65)
=32.5 units²
So, add the two areas of each shape:
35 + 32.5 = 67.5 units².
First, we calculate the radius of the circle.
radius=diameter / 2
radius=44 ft / 2=22 ft.
Second; we calculate the area of a circle.
area of a circle=πr²
area of a circle=π(22 ft)²=484π ft²
Remember: 22²=22 * 22 =484
Answer: B) 484π ft²
7x + 15x + 27 = 247
22x = 247 -27
22x =225
X= 10.22
