The height of a can is 3 times its radius. If the radius of the can is 3 centimeters, what is the volume?

Semmy [17]

Answer:

Step-by-step explanation:

If the height is 3 times the radius you can find that by: 3r

r = 3.

So: 3 x 3 = 9

The height is 9 centimeters

Volume of a cylinder (can):

$V= 2\pi rh$

Plug in what we know

$V = 2 \pi (3) (9)\\V = 54\pi \\V = 169.646\\$

Rounds to: 170

A rowing team rowing with the current traveled 36 km in 3 h. Rowing against the current, the team rowed 12 km in the same amount

alex41 [277]

Answer:

team: 8 kph
current: 4 kph

Step-by-step explanation:

The downstream speed is ...

speed = distance / time

speed = 36 km/(3 h) = 12 km/h

The upstream speed is ...

12 km/(3 h) = 4 km/h

If b and c represent the speeds of the boat and current, respectively, then we have ...

b + c = 12

b - c = 4

Adding these gives ...

2b = 16

b = 8

c = b -4 = 4

The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.

Bingel [31]

Answer:

$\Delta s = 1$

Step-by-step explanation:

The length of the arc is directly proportional to the angle of the arc, whose measure is determined by simple rule of three:

$\Delta s = \left(\frac{60^{\circ}}{360^{\circ}} \right)\cdot (6)$

$\Delta s = 1$
