The formula for finding the area of a sector of a circle is a=πr^2(x/360) , where r is the radius of the circle and x is the measure of the central angle of the sector. solve for x.  x=360πr2ax=360aπr2x=a360πr2x=aπr236 0

A = π r²

360A = π r² x

B

what is the question?

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
