Answer 2

need the area

Answer 3

actually my bad, doesn't look like a circle though.

Answer 4

okk

Answer 5

anyway,
area = integral (1/2) (5 + cos(theta))^2 dtheta, from 0 to 2pi

Answer 6

try
\[\int\limits_{0}^{2\pi} 0.5(5+\cos \theta)^2d\]

Answer 7

do the math and area = (51/2)pi

Answer 8

which is what she said

Answer 9
