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.

What are the x-intercept and y-intercept of the graph of y=13x−6 ?

gtnhenbr [62]

To find the x-int., let y = 0 and solve for x: 13x = 6, so x = 6/13: (6/13, 0)

To find the y-int., let x =0 and read off the y-int: (0, -6)
