Find the volume of a cone with a base radius of 3 cm and a height of 9 cm

katovenus [111]

The volume of a cone is 84.78 cm

Step-by-step explanation:

Given:

radius = 3 cm and

height = 9 cm

To Find:

The Volume of a Cone

Formula:

The Formula for the volume of a cone is

V=πr2 *h/3

Solution:

V=πr2 *h/3

π value is 3.14

V= 3.14*(3)^2*9/3

V=3.14*9*3

V= 84.78 cm

Therefore the volume is 84.78 cm.

Let the sample space be S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Suppose the outcomes are equally likely. Compute the probability of

Crazy boy [7]

Answer:

The probability is 3/5

Step-by-step explanation:

Given,

Sample space, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10},

⇒ n(S) = 10,

Odd numbers less than 7 = 1, 2, 3, 4, 5 and 6

i.e. E = {1, 2, 3, 4, 5, 6}

⇒ n(E) = 6,

$\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

So, the probability of the event E,

$P(E) =\frac{n(E)}{n(S)}$

$=\frac{6}{10}$

$=\frac{3}{5}$

Ken and Hamid run around a track. It takes Ken 80 seconds to complete a lap. It takes Hamid 60 seconds to complete a lap. Ken an

likoan [24]

The correct answer is:

Ken will have run 3 laps and Hamid will have run 4.

Explanation:

To find this, we first find the number of seconds that will have passed when they meet again. We use the LCM, or least common multiple, for this. First we find the prime factorization of each number:

80 = 10(8)

10 = 5(2)

8 = 2(4)

4 = 2(2)

80 = 2(2)(2)(5)(2)

60 = 10(6)

10 = 5(2)

6 = 2(3)

60 = 2(2)(3)(5)

For the LCM, we multiply the common factors by the uncommon. Between the two numbers, the common factors are 2, 2 and 5. This makes the uncommon 2, 2, and 3, and makes our LCM

2(2)(5)(2)(2)(3) = 240

This means every 240 seconds they will both be at the start line.

Since Ken completes a lap in 80 seconds, he completes 240/80 = 3 laps in 240 seconds.

Since Hamid completes a lap in 60 seconds, he completes 240/60 = 4 laps in 240 seconds.
