Step-by-step explanation:
Answer:
3 pyramids.
Step-by-step explanation:
The volume of one pyramid is 1/3 * b^2 * h
= 1/3 * 12^2 * 25
= 1200 cm^3.
The volume of one ball bearing = 4/3 * π * 0.7^3
= 1.43676 cm^3.
Therefore the volume of 2490 ball bearings = 2490 * 1 .43676
= 3577.53 cm^3.
So we need 3577.53 / 1200 = 2.98 = 3 pyramids.
Answer:
125.6 units = x
Step-by-step explanation:
72
---- = tan 37 degrees, so x = 72/(tan 37 degrees)
x
This comes out to x = 72/0.573 = 125.6 units = x
