Remark

An angle bisector sets up a triangle ratio that looks like the following proportion.

3x - 3 5x

====== = ====== Cross multiply

24 44

44*(3x-3) = 24*5x Remove the brackets on the left

132x - 132 = 24*5x Combine the right side

132x - 132 = 120x Add 132 to both sides

132x = 120x + 132 Subtract 120x from both sides

132x- 120x = 132 Combine

12x = 132 Divide by 12

x = 11

Answer:

4:25

Step-by-step explanation:

Given that,

r₁ = 15 inches, r₂ = 6 inches

The area of the cylinder is given by :

$A=2\pi rh+2\pi r^2$

The ratio of surface areas of two cylinders,

$\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}$

Hence, the required ratio is 4:25.
