Answer:

The number of yards in 5 miles will be: 8800 miles

Step-by-step explanation:

The double numbers line shows the ratio of yards to miles.

From the number line, it is clear that

at 2 miles, the number of yards is 3520.

Thus,

The unit rate = 3520 yards / 2 miles

= 1760 yards / per mile

Thus, the number of yards in 5 miles will be:

1760 × 5 = 8800 miles

Therefore, the number of yards in 5 miles will be: 8800 miles

This semicircle has a diameter of 5 meters.

Ira Lisetskai [31]

Area of semicircle is given by:
$A_sc = \frac{1}{2} \pi r^2$

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):
$A_t = \frac{1}{2}(3.14)(2.5)^2 = 9.81m^2$

So, the area of this semicircle is 9.81m².
