Four friends share 3 sheets of construction paper equally. What fraction
of a sheet of paper does each friend get?

Answers

Answer:

0.75 or 3/4 sheet of paper

Answer:

3/4 of each sheet

Step-by-step explanation:

You have to divide the number of sheets of paper by the number of people sharing them, which gives you 3/4. This makes sense because if there are more people than paper, each person will get less than a full sheet.

To the nearest tenth of a centimeter, how tall is a cylinder with a radius of 8.4 cm and volume of 3119.5 cm3. Give the approximate answer rounded to 2 decimal places.

Thank you!

Answers

Answer:

r=8.4cm

v=3119.5cmcube

volume of a cylinder

=pie r square height

pie=22/7

22/7×8.4×8.4×h=3119.5cm cube

221.76cmsquareh=3119.5cm cube

___________________________

221.76cm square(both sides)

h=14.07cm

The height of the cylinder is h = 14.09 cm

Given data:

To find the height of the cylinder, the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height.

Given that the radius is 8.4 cm and the volume is 3119.5 cm³, substitute these values into the formula and solve for h.

3119.5 cm³ = π(8.4 cm)²h

To isolate h, divide both sides of the equation by π(8.4 cm)²:

h = 3119.5 cm³ / (π(8.4 cm)²)

Now, calculate the approximate value of h as:

h ≈ 3119.5 / (π * 8.4²)

≈ 3119.5 / (3.14 * 70.56)

≈ 3119.5 / 221.1264

≈ 14.0989 cm

Hence , the height is 14.09 cm
