Answer:
7:5
Step-by-step explanation:
The ratio of the circumference of two semicircles will be
Given data :
The ratio of the area of two semicircles is 49:25.
Let,the radius of two semicircles = r and R.
So,
(πr²)/2 : (πR²)/2 = 49:25
(πr²/2) × (2/πR²) = 49:25
r²/R² = (7)²:(5)²
r:R = 7:5
The ratio of circumference
πr : πR = (π×7)÷ (π×5)
= 7:5
