Question

A circular area is hundred times that of another circular area. Find the ratio of their
circumference​

Answer 1

Answer:

et the area of two circles be R1 and R2.

R1:R2 = 10:1.

Hope this helps!

Step-by-step explanation:

Answer 2

Answer:

let 1st area =A1 = πr^2

and 2nd area = A2= πR^2

from question

100×A1 = A2

100×πr^2 = πR^2

100×r^2 = R^2

taking under root both sides

√(100×r^2) = √(R^2)

10×r = R

2×π×10×r = 2×π× R

2πr÷2πR = 1÷10

Ratio is 1:10
