Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.

Mama L [17]

Answer:

Step-by-step explanation:

RS + ST = RT

6y + 3 + 4y + 7 = 60

6y + 4y + 3 + 7 = 60

10y + 10 = 60

10y = 60 - 10

10y = 50

y = 50/10

y = 5

RS = 6*5 + 3 = 30 +3 = 33

ST = 4*5 + 7 = 20 + 7 = 27

The height of a cylinder is 8 centimeters. The circumference of the base of the cylinder is 20π centimeters. Which measurement i

trapecia [35]

Answer: $2514.28\ cm^3$

Step-by-step explanation:

Given

The height of the cylinder is $h=8\ cm$

Circumference of the base is $20\pi \ cm$

suppose 'r' is the radius of the cylinder

$\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm$

The volume of a cylinder is $V=\pi r^2h$

$\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3$
