An urn contains 8 pink and 5 red balls. Six balls arerandomly drawn from the urn in succession, with replacement.That is, after

slega [8]

0.088

Step-by-step explanation:

The total number of balls in the urn is;

8 + 5 = 12

Because the pink balls are 8, then the probability of picking a pink ball from the urn is;

8/12

To get the probability that all 6 balls drawn from the urn are pink, we will use the AND probability rule of the mutually exclusive events which means we’ll multiply the probabilities of each of the six pink balls;

8/12 * 8/12 * 8/12 * 8/12 * 8/12 * 8/12

= 0.088

sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya

madreJ [45]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = $\frac{d}{2}$

= $\frac{18}{2}$

= $9 \ cm$

Height,

h = 20 cm

As we know,

⇒ Area of a cone = $\frac{1}{3} \pi r^2 h$

On substituting the given values in the above formula, we get

⇒ = $\frac{1}{3}\times 3.14\times (9)^2\times 20$

⇒ = $\frac{1}{3}\times 3.14\times 81\times 20$

⇒ = $3.14\times 27\times 20$

⇒ = $1,695.6 \ cm^3$
