Question

the ratio of areas of two circles is 1:4, then find ratio of their radii.

Answer 1

Let the radius of the first circle be R and the radius of the second circle be r.

According to problem,

πR² : πr² = 1 : 4
=> πR²/πr² = 1/4
=> R²/r² = 1/4
=> R/r = √1/4 = 1/2

⚡️⚡️⚡️⚡️ THEREFORE, THE RATIO OF RADIUS OF THOSE TWO CIRCLES IS 1 : 2 ⚡️⚡️⚡️⚡️
