Can someone solve this! Need it done soon
Airida [17]

Answer:

117.5 ft²

Step-by-step explanation:

To find the area of the shaded area, we can find the area of the square, then subtract the areas of the two semicircles.

First, we will find the area of the given square, by using the formula lw, multiplying the length and width. The dimensions of this square are 14×14.

14 · 14 = 196

The area of the square is 196 ft².

We can now find the area of the two congruent half-circles. Since they are identical, we can simply find the area of one circle if it was whole. To find the area of a circle, we'll use the formula A=\pi r^2. With some simple deduction, we can see that the diameter of the circle is 10 ft, so the radius would be 5 ft long. Plug our values into the formula.

A = \pi5²

We will use 3.14 for \pi.

A = 78.5

The area of both the semicircles is 78.5 ft².

Now, we can subtract.

196 - 78.5 = 117.5

The area of the figure is 117.5 ft².

Good luck ^^

Express the ratio 7 days to 6 weeks as a decimal fraction​
Mashcka [7]

Answer:

0.166

Step-by-step explanation:

We know that,

1 week = 7 days

i.e.

6 week = 7(6) days = 42 days

We need to express ratio 7 days to 6 weeks as a decimal fraction​. So,

R=\dfrac{7\ \text{days}}{42\ \text{days}}=\dfrac{1}{6}\\\\=0.166
