Solution:
we have given the length of the rectangular card-

and, width-

now, the area of the card will be- length×width.
so, we have-

we also have given the length of ribbon-

and, width-

so, area of the ribbon is-
length×width

now the area of shaded gray region will be-

Hence, the required expression would the above expression.
Answer:
im not 100% but i think its
T= 2t-4+(t-4)+7
Answer: 24times
Step-by-step explanation:
Formula for the volume of a cylinder = πr²h
Volume of the cone = 1/3πr²h
Therefore the volume of the cylinder = 22/7 x 10² x 20
= 22/7 x 10 x 10 x 20
= 6285.71cm³
Therefore , the volume of the cone = 1/3 x 22/7 x 5² x 10
= 1/3 x 22/7 x 5 x 5 10
= 5500/21
= 261.9cm³
Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water = 6285.71/261.9
= 24times.
That equals 3871 hope it helps
