lemme talk to you real quick about sectors of circles.

Formulas: k=1/2r^2(theta) s=r(theta)
or
k=1/2 rs

k=area of a sector
r= radius
theta= central angle
s=arc length

Not much explaining to do besides juat plug into the formula

Ex: s sector of a circle has arc lenth 4cm and are 20 cm^2. Find radius and central angle.

s=4
k=20
r=?
theta=?

r=2k/s= 2(20)/4 r=10

4=10(theta) theta= 5/2

there it is boi. Ricky G done with the christmas blogs
