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.

The coordinates of prs are p(-3,2), R (2,5), s (0,0) which of the following could be p'r's' after a 270 degree rotation

Ksju [112]

Formula for 270 degree rotations:
(x,y) -----> (-y,x)

So....

p: (-3,2)----> (-2,-3)
r: (2,5)------>(-5,2)
s: (0,0) ------> (0,0)
