Hi,
The like terms are 2xy, -xy and (1/2)xy, since they have the same variables and powers.
To solve this problem you must apply the formula for calculate the surface area of a circle, which is shown below:
SA=πir^2
where r is the radius of the circle
r=18 inches
By substituying values, you have that the surface area is:
SA=π(18 in)^2
SA=324π in^2
The answer is 324π in^2
Its Your option B.
i.e. 1.325 * 10 ^ 6
Answer:
6 i think double check though
