NEED ASAP!! A round of pie 10inches in diameter is cut into a slice with a 30 degree angle.

Question

use the formula Α= 1/2 r²θ. to find the exact area of the slice. (hint: what crucial piece of information about the formula above was not mentioned?)

Answer 1

r = 5 in (half of diameter)

A = 1/2 (5)^2 (π/6) = 25π/12 in^2

θ must be in radian
