Question

19. Solve for r: C=2pi r
A) R=C/2pi
B) R=2Cpi
C) R=2pi/C
D) R=1/2Cpi

Answer 1

The correct answer is: [A]: " {r = C / 2 pi} " .
________________________________________________
Step-by-step explanation:
________________________________________________
Given:
_____________________________________________________
" C = 2 * pi * r " ; isolate "r" on one side of the equation ;

Divide EACH SIDE of the equation by: "2 * pi " ;

C / (2 * pi) = (2 * pi * r) / (2 * pi) ;

C / (2 * pi) = r ;

↔ r = C / (2 * pi) ; which is: Answer choice: [A]: " {r = C / 2 pi} " .
