Question

if the ratio between the radius of two circle is 3:4 then find out their ratio in between area ? ​

Answer 1

Answer:

9:16

Step-by-step explanation:

Ratio of radius = 3:4

Let R1 be 3x and R2 be 4x

Area of circle =πr²

π(R1)²/π(R2)²

(3x)²/(4x)²

9x²/16x²

9/16

Therefore ratio of area of circles is 9:16

Answer 2

Answer:

heyyy,

r₁/r₂ = 3/4, where r₁ is the radius of one of the circles (the smaller one), and r₂ is the radius of the other circle. So, as it can be seen, if the ratio of the radii of two circles is 3:4, then the ratio of the areas of the same two circles is 9:16.

Step-by-step explanation:

Let R1 be 3x and R2 be 4x

Area of circle =πr²

π(R1)²/π(R2)²

(3x)²/(4x)²

9x²/16x²

9/16
