Answer:

juliet collected 50 cans

Step-by-step explanation:

let x be rosanas cans

10+x+2x = 130

simplify

10 + 3x = 130

3x = 130 - 10 = 120

x = 120/3 = 40

rosanas cans = 40

juliets cans = 40 +10 = 50

santiagos cans = 50 x 2 = 100

but i think the question is wrong!!

Hello!

To find the volume of a cylinder you use the equation

$\pi r^{2} h$

r is radius
h is height

Put in the values you know

$\pi * 5^{2} *10$

square the 5

$\pi *25*10$

Multiply the 10 and 25

$250 \pi$

The answer is D) $250 \pi in^{3}$

Hope this helps!
