The length of a shadow of the building is 36m. the length of the pole, which is perpendicular to the ground, is 1.9m. the length of the pole's shadow is 1.52m. what is the height of the building?

45

Step-by-step explanation:

We are assuming that the pole's shadow and buildings shadow are proportional so our ratio is

x/36=1.9/1.52

cross multiply

1.52x=68.4

simplify

x=45

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

24+x=y
