Answer:
31.869 kg.
Step-by-Step Explanation:
Inner radius,r=12/2=6cm
thickness=1cm
so,outer radius,R=6+1=7cm
height,h=1m=100cm
volume=pi×(R^2-r^2)×h
=22/7×(7^2-6^2)×100
=22/7×(49-36)×100
=22/7×13×100
286/7×100
=28600/7
since,density=7.7gm/cm^3
also,weight=volume×density
weight=28600/7×7.7gm
=31460gm
or,31.46 kg
Answer:
The graph which shows the line y-1=2(x+2) is shown in the attachment
P=2q P=angle p
180=p+2q Q=angle q
180=2q+2q
180=4q
180(1/4)=4q(1/4)
45=q
P=2q
P=2(45)
P=90
A. is the answer and is false
proof 5 x 5 =25 Both 5s are rational and so is 25
√4 x √4 = √16 = 4 All are rational.
