I think it’s about 134.13 ft

to find the circle the formula is pi times the radius squared so:
12.5 x 12.5 = 156.25
156.25 x pi ≈ 490.8738 ft squared

to find the square it’s base x height so:
25 x 25 = 625

then to find the shaded part you just find the difference:
625 - 490.87 = 134.13 ft

Answer:

The ratio of Trucks to Cars is

$3: 14$

The ratio of Hot Dogs to Hamburgers is

$3 : 5$

Step-by-step explanation:

There are 42 cars and 9 trucks, and since they asked to write the ratio of trucks to cars, we write it as they asked. Therefore the ratio would be

$9 : 42 \\ \\ \frac{9}{3} : \frac{42}{3} \\ \\ = 3 : 14$

There are 24 hotdogs and 40 hamburgers, since they asked us to write the ratio of hotdogs to hamburgers we are going to write it as it was said. Therefore the ratio is

$24 : 40 \\ \\ \frac{24}{8} : \frac{40}{8} \\ \\ = 3 : 5$
