Answer:

25.13 cm

Explanation:

Mrs. Lynn's art class is making pencil holders out of soup cans

These soup cans are definitely in cylindrical forms.

Each student is first covering a can with felt.

A felt is a type of material that is used for covering other objects. Here a felt is used to cover soup cans.

So if the diameter of the bottom of the can is 8 cm (i.e d = 8cm)

What will the circumference of the piece of felt need to be in order to cover the bottom of the can?

The felt will also take the circumference of a cylinder; and which is given by the expression

C = 2 πr

since diameter (d) = 8 cm

radius (r) = \frac{d}{2}

r = \frac{8}{2}

r = 4 cm

C = 2 × π × 4 cm

C = 2 × 3.142 × 4 cm

C = 25.13 cm

∴ the circumference of the piece of felt need to be 25.13 cm in order to cover the bottom of the can.

lesya [120]

Answer:

100\ \text{meters}.

Explanation:

Distance Skylar traveled North is 50\ \text{meters}

Then she traveled 30\ \text{meters} Westward.

After which she traveled 20\ \text{meters} towards the South.

The total distance traveled would be the sum of the distances.

50+30+20=100\ \text{meters}

The distance traveled by Skylar was is 100\ \text{meters}.

An 80.0 N force accelerates a 6.0 kg object from 4.0 m/s to 8.0 m/s. What is the
kolezko [41]

Answer:

24kgm/s

Explanation:

Given parameters:

Force  = 80N

Mass of object  = 6kg

Initial velocity  = 4m/s

Final velocity = 8m/s

Solution:

Impulse  = ?

Solution:

The impulse on a body is its change in momentum.

    Impulse  = m (v  - u )

m is the mass

v is the final velocity

u is the initial velocity

  Now insert the parameters and solve;

          Impulse  = 6 (8 - 4) = 24kgm/s

dado los vectores a=3.5 b=4 c=6.5 , si se sabe que a+b+c=0 (resultante) cual es el angulo formado por A y B?
lawyer [7]

cos(A) = (b2 + c2 − a2) / 2bc = (16+6.5^2-3.5^2)/(2*4*6.5) = 0.88461538  so A = cos−1 (0.88461538) = 27.79 Deg cos(B) = (c2 + a2 − b2)/2ca = (3.5^2+6.5^2-16)/(2*3.5*6.5) = 0.84615385  so B = cos−1 (0.84615385) = 32.2 Deg
