Answer:

V = 565.5

Step-by-step explanation:

<u>Cylinder Formulas in terms of r and h</u>

Calculate the volume of a cylinder: V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside): L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2

Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Which ratio represents the value of sin Q

Volgvan

We know that :

$\bigstar \ \ \boxed{\sf{sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}$

From the figure, We can notice that :

↔ Opposite side of Angle Q is 9 units

↔ Hypotenuse is 15 units

$\sf{\implies sinQ = \dfrac{9}{15}}$

$\sf{\implies sinQ = \dfrac{3}{5}}$

blagie [28]

Answer:

-3x and -6x

Step-by-step explanation:

Take a look at the missing spaces. Multiply -6 with x which equals -6x

Multiply -3 with x which equals -3x

Therefore, the answer is B, -3x and -6x
