Answer:
A. 1/4 as large
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
Cut the radius in 1/2
V = pi (1/2r)^2 h
V = pi (1/4) r^2 h
V = 1/4 pi r^2 h
The volume is 1/4 what is was before we cut the radius in 1/2
Answer:
Rs 720.

Answer:
It is proved that AB = 2 × DE.
Step-by-step explanation:
The three vertices of triangle ABC are A(-2,6), B(8,-2) and C(-8,-4).
So, the mid point of AC (say D) has coordinates .
And the mid point of BC (say E) has coordinates .
Now, the length of DE will be units.
Again, the length of AB will be units.
So, it is proved that AB = 2 × DE. (Answer)
