Tina should make 31 inch tall model to replicate 155 feet tall monument.
Step-by-step explanation:
This problem can be solved by direct unitary methods easily-
Firstly, Scale is the ratio of the dimension of the original substance to the dimension of a model
Scale= original dimension/ model dimension
Model is the miniaturised representation of a substance.
The monument is 155 feet tall
Tina replicates it with a scale 1inch: 5 feet
Thus, this means that Tina would need 155*1/5 = 31 inch tall model to replicate the complete length of the monument.
Hence Tina needs to make 31-inch tall model.
113.04 is the volume
V = pi x r^2 x h
3.14 x 2^2 x 9 = 113.04
Answer:
26
Step-by-step explanation:
Sydney = x
Devaughn = 2x
x + 2x = 78
3x = 78
x = 78 / 3
x = 26
