42:35 or if simplified 6:5
The way to determine the number of solutions is to complete the problem in multiple different ways.
The answer is c bc I just know
Answer:
5 meters
Step-by-step explanation:
because 100 meters divided by the base equals the Height so 100 divided by 20 = 5
Answer:
Ix = Iy =
Radius of gyration x = y = 
Step-by-step explanation:
Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.
Mass of disk = ρπR2
Moment of inertia about its perpendicular axis is
. Moment of inertia of quarter disk about its perpendicular is
.
Now using perpendicular axis theorem, Ix = Iy =
=
.
For Radius of gyration K, equate MK2 = MR2/16, K= R/4.
