PLEASE I NEED HELLP A football field is shaped like the diagram shown. It is a rectangle with semicircles at the two ends. A running track will be designed to go around the field. What will be the area, in square centimeters, of a model of the running track that has a ratio of 1 cm to 1 m?

A. 490,30
B. 980.30
C. 500.30
D. 1480.30

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
