A cylindrical syringe has a height of 6.8 cm and a diameter of 2.37 cm is going to be
alukav5142 [94]

Answer:

The number of syringe filled with water that would be needed to fill the semi-sphere is approximately 8.714 syringes

Step-by-step explanation:

The height of the syringe = 6.8 cm

The diameter of the syringe = 2.37 cm

The circumference of the hemisphere = 31.4 cm

Let r represent the radius of the hemisphere, we have;

2·π·r = 31.4 cm

r = 31.4/(2 × π) ≈ 4.9975 cm

The volume of the hemisphere = 2/3 × π × r³ = 2/3 × π × (31.4/(2 × π))³ ≈ 261.4 cm³

The volume of the syringe = π × d²/4 × h = π × 2.37²/4 × 6.8 ≈ 29.998 cm³

The number of syringe filled with water that would be needed to fill the semi-sphere = (The volume of the hemisphere)/(The volume of the syringe)

Therefore;

The number of syringe filled with water that would be needed to fill the semi-sphere = 261.4 cm³/(29.998 cm³) ≈ 8.714 syringes.

Solve the following system of equations
Ipatiy [6.2K]

Answer:

The solutions are (0, 4) and (0, -4)

Step-by-step explanation:

Solve this system using substitution:  

Take the negative of the first equation and add the result to the second one:

-x^2 + y^2 = 16 becomes x^2 - y^2 = -16

Then:

x^2    - y^2 = -16

-2x^2 + y^2 = 16

------------------------

-x^2 = 0, so x must be 0.

By the first equation, if x = 0, -(0)^2 + y^2 = 16, or

y^2 = 16, or y = ±4

The solutions are (0, 4) and (0, -4)
