The length of the shadow is about 20.2( rounded to the nearest tenth), because the shadow and the building formed as a triangle, so uses the formula of Pythagorean theorem to solve this problem

Mathematics

19.63 inches

Step-by-step explanation:

The area of a circle is found by using the formula

A = πr²

r is the radius of the circle, which is the diameter divided by two.

D = 5 in so r = D ÷2

5 ÷ 2 = 2.5 inches for the radius.

A = π (2.5)²

A = π (6.25)

A = (3.14)(6.25)

A = 19.625 inches
