Area of a circle is πr^2.
From this, we can calculate
π*2.5^2
= π*6.25
= 19.625
= 19.6
The rope would be 3 yards long because every 3 feet is equal to 1 yard
the first picture you have to use B X L X H ( base, length and height) and i got 1728 mm^3
for the second one, you have to use the formula L X H ( P+ Q/2) ( length times height times the product of the base width plus the top width divided by 2 and i got the answer of 196 m^3.
i hope this helps :)
