Answer 2

9.8

Answer 3

well first off I think the formula you used is a little off

area of a sector = [ (angle of sector)/2pi ] * pi * r^2
[since it's in radians]

to write something in terms of pi, you would simplify everything except pi, then just stick a pi symbol at the end

Answer 4

actually nvm your formula is right

Answer 5

but anyway, yeah, since you have (1/2)5^2 * (1/4) * pi you would just simplify the (1/2)(5^2)(1/4) part then just write pi at the end

Answer 6

so 25/8 pi ?

Answer 7

yes

Answer 8

can it also be in decimal form?

Answer 9

it asks for both, so you would write 25pi/8 ~and~ whatever that's equal to in decimal form
