Answer:
78.5
Step-by-step explanation:
The diameter (d) is equal to the radius x 2, so take half of d to get r. Use r (5) in the equation to get your answer.
A= 3.12 x 5^2
A= 78.5
Answer:
The total length is 1123 feet.
a) if the model is 30 inches long, the first thing we need to do is write inches in feets, so 1 feet is equivalent to 12 inches.
so 30 inches are 30/12 = 2.5 feets.
the scale is the ratio between the feets in the the two lengths.
1123/2.5 = 449.2
so the scale is 1:449.2
so each feet in the model is equivalent to 449.2 feets in the enterprise.
b) if the model is 2 feet long, then:
1123/2 = 561.5
the scale is 1:561.5
so each feet in the model is equivalent to 561.5 feets in the enterprise.
