Answer:
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

A stadium has central rectangular area 125m long by 80 m wide there are two semicircular ends.running tracks goes all way round
olga_2 [115]

) Using formula for cicumference.

Circumference = Pi * diameter

Circumference = Pi * 80m

Circumference = 251.2m.

Total inside length of the curved ends.

2)Total distance round inside of track =

2(125) + 251.2m

= 250 + 251.2

= 501.2m

3) Area of circular ends =

Pi*r^2

= Pi*40^2

= 5024m^2

Area of central area (rectangle)

length * width

125m * 80m

= 10,000m^2

Total area inside track =

5,024m^2 + 10,000m^2

= 15,024m^2

Hope this helps.
