Answer 1

First, since the diameter of the pool cover is 18ft, the circumference can be found with the following equation:

$C=\pi\cdot d$

then, the circumference is:

$C=3.14\cdot18=56.52ft$

next, we can find the area with the following formula:

$A=\pi\cdot r^2$

since the radius of the pool cover is 9 ft, we have:

$A=(3.14)(9)^2=(3.14)(81)=254.34ft^2$

therefore, the circumference is 56.52ft and the area is 254.34ft^2
