A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm. Calculate the volume of
never [62]

Answer:

The volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

Step-by-step explanation:

Formula

Volume\ of\ a\ cylinder = \pi r^{2} h

Volume\ of\ a\ cone = \pi r^{2} \frac{h}{3}

Where r is the radius and h is the height .

As given

A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm.

\pi = 3.14

Thus

Volume\ of\ a\ cylinder =3.14\times 5\times 2\times 2

                                             = 62.8 cm³

Thus the volume of a cylinder is 62.8 cm³ .

Volume\ of\ a\ cone = 3.14\times 2\times 2\times frac{5}{3}

Volume\ of\ a\ cone =\frac{5\times 3.14\times 2\times 2}{3}

Volume\ of\ a\ cone =\frac{62.8}{3}

                                        = 20.9 (Approx) cm³

Thus the volume of a cone is 20.9 cm³ .

Therefore the volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .

I need help with #11 and #17 PLEASE​
shutvik [7]

Answer:

11.   ∠B    ∠ABC     ∠CBA     ∠2

17.    QR = 12

Step-by-step explanation:

11.   ∠B    ∠ABC     ∠CBA     ∠2

17.    Given:  PS = 18     PR = 15      PQ ≅ RS

       It would be good if you could draw a picture for yourself

So, RS  = PS - PR

             = 18 - 15 = 3

       RS = PQ = 3

        QR = PS - RS - PQ

              = 18 - 3 - 3

              = 12
