Question

There is direct variation between the circumference and the radius of a circle. When the circumference is 22 cm, the radius is 3.5 cm. What is the circumference, if the radius is 35 cm?
(1) 220 cm (2) 110 cm (3) 77 cm (4) 440 cm​

Answer 1

Answer:

option 1

Step-by-step explanation:

$c = 2\pi \: r \\ \\ c \alpha r$

Answer 2

Answer:

Circumference = 2πr

(c)

C1 / C2 = r1 / r2

22 / C2 = 3.5 / 35

C2 = 22 x 35 / 3.5

C = 220 cm
