The Willis Tower (formerly known as the Sears Tower) in Chicago is about 1454 feet tall . A model of it has a scale of 2 in = 45 feet. How tall is the model?

1. Let's review the information given to us to answer the question correctly:

Height of the Willis Tower in Chicago = 1,454 feet

Scale of the model = 2 inches : 45 feet height

2. How tall is the height?

For answering that question, we will use the following expression:

Height of the model = Height of the Willis Tower in Chicago/Scale in feet * Scale in inches

Replacing with the real values, we have:

Height of the model = 1,454/45 *2

Height of the model = 32.31 * 2 = 64.62 inches

64.62 inches/12 = 5.39 feet

The model is 64.62 inches of height or 5.39 feet

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
