Question

find the ratio of a circumference of two circle whose radius are in the ratio 4 is to 5 with fuul sol​

Answer 1

r1=4 r2=5

then ratio of circumference is

2×22/7×4÷2×22/7×5

4/5

4:5

Answer 2

Answer:

4 : 5

Step-by-step explanation:

CIRCUMFERENCE OF FIRST CIRCLE = 2 X 22/7 X 4

=176/7

CIRCUMFERENCE OF SECONF CIRCLE = 2 X 22/7 X 5 = 220/7

RATIO = 176/7 : 200/7

= 176 : 200 = 4 : 5
