Answer:
weight of a water=0.5
spherical ball is filled With water=0.95.
so dear for
22\7*0.5*0.95=1.49
For cylinder
d=10m
So r=5m
h=5m
volume=pi×r^2×h
=3.14×5×5×5
=3.14×125
=392.5m^3
So option a is correct.
This is a typical algebra problem pretending to be geometry. The two indicated angles are supplementary, adding to 180 degrees, precisely when the lines are parallel.
It's not really indicated, but the 8 and the 2 are in units of degrees.
6x + 8 + 4x + 2 = 180
10x = 170
x = 17 degrees
Answer:
a) 50 degrees
b) 21 degrees
c) 64 degrees
d) 70 degrees
e) 105 degrees
