You payed less because 1.69x4 is 6.76 which is more than 5 dollars
The 10 pound box has the lower price pound because it cost $0.97 per pound while the 5 pound box cost $1.05 per pound.
so use a basic formula here:
area of a circle = πr²
and the circumference of a circle = πd
a)
therefore the area of the pool cover is π multiplied by the radius² (which is the diameter of the pool cover plus the extra 12 inches divided by two, so the radius is 21/2 or 10.5) is 346.36(to two decimal places.)
b)
Using the same diameter, we can work out the length of the rope by multiplying the diameter (10.5) by π, which is 32.99 (to two decimal places).
