I’ll give the Brainliest to who answers this question with a reasonable explanation.

Answer:

143.8\:\mathrm{ft^2}

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): \frac{1}{2}\cdot 4.5^2\cdot \pi

Area of trapezoid (average of bases multiplied by height): 16\cdot 7

Thus, the total area of the figure is:

\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}

Evaluate the expression described below if the number is 4. The difference between a number squared and the number. A. 0 B. 4 C.
svet-max [94.6K]
What the above statement is saying is:
If the number is 4, find the difference between the square of the number (the number is 4) and the number itself (the number is still 4).

The square of the number is:
The number^2
= 4^2
= 4 × 4
= 16

The difference between the square of the number and the number is:
The number^2 - The number
= 16 - 4
= 12

Hope this helps! :)
