Question

the ratio of the circumference and diameter of a circle is 22 is 7. if the length of the diameter of the circle is 2 metre 1 dcm lets calculate its circumference​

Answer 1

Step-by-step explanation:

LET THE circumference BE 22x and the diameter be 7x

GIVEN-

DIAMETER = 2metre and 1 decimetre(dcm)

(2×10)dcm+1dcm

21dcm. ( 1metre=10 dcm)

Now, we get DIAMETER 7x= 21dcm

x = (21/7)dcm

x= 3dcm

in the first, the circumference is 22x and x = 3 dcm

then circumference = 22×3= 66dcm.

OR 6 METRE 6dcm
