Radius of ball is 6in. What is the volume?

Lina20 [59]

Radius of ball is 6 inches. Then the volume is 904.32 $in^3$

Solution:

Given that, radius of a ball is 6 inches.

We have to find the volume of the ball with 6 inches radius.

Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.

The volume of sphere is given as:

$\text { volume of sphere }=\frac{4}{3} \pi r^{3}$

where r is the radius.

Here in our problem, r = 6

$\text { Then, volume }=\frac{4}{3} \times \pi \times 6^{3}$

$\begin{array}{l}{=\frac{4}{3} \times \pi \times 6 \times 6 \times 6} \\\\ {=4 \times \pi \times 2 \times 6 \times 6} \\\\ {=8 \times \pi \times 36} \\\\ {=288 \pi=288 \times 3.14=904.32}\end{array}$

Hence the volume is 904.32 $in^3$

Anastaziya [24]

Answer:

a) P(X ≤ 4) = 0.9

b) P(X>7) = 0

c) P(X ≤ 5) = 0.9

d) P(X>4) = 0.1

e) P(X≤2)= 0.7

Step-by-step explanation:

Hello!

Given the distribution of cumulative probability

0 for X < 1

F(x) 0.7 for 1 ≤ X < 4

0.9 for 4 ≤ X < 7

1 for 7 ≤ X

To determine each of the asked probabilities you have to select the probability corresponding to the defined intervals for X:

a) P(X ≤ 4) = 0.9

This value of X is included the interval "4 ≤ X < 7" so the corresponding probability is 0.9

b) P(X>7) = 0

This is equal to the expression:

1 - P(X≤7)

This expression is included in the last interval so the probability is 1

1 - 1 = 0

c) P(X ≤ 5) = 0.9

5 is included in the third interval "4 ≤ X < 7" so the corresponding probability is 0.9

d) P(X>4) = 0.1

P(X>4) = 1 - P(X≤4)

P(X≤4) is in the interval of definition "4 ≤ X < 7" so the corresponding probability is 0.9

1 - 0.9 = 0.1

e) P(X≤2)= 0.7

The value X=2 is included in the second interval "for 1 ≤ X < 4", so the probability is 0.7

I hope it helps!
