Volume formula of a sphere:
\frac{4}{3}\pir³

given:
r = 3 

V = \frac{4}{3}\pi(3)³
V = \frac{4}{3} × 27\pi
V = 36\pi units³ (in terms of \pi)
V = 113.097 units³ ≈ 113.1 units³

Using the slot method and multiple cases, calculate the probability that you would roll 3 sixes.
kotegsom [21]

Answer:

P = 1/216

the probability that you would roll 3 sixes is 1/216

Step-by-step explanation:

For a given dice, there are six possibilities.

We have;

1,2,3,4,5,6

The probability of rolling a six(6) is;

P(6) = 1/6

Then, the probability of rolling 3 sixes is a multiple of the P(6), given as;

P = P(6) × P(6) × P(6)

P = 1/6 × 1/6 × 1/6

P = 1/216

the probability that you would roll 3 sixes is 1/216

If Ms. P wants to withdraw $900 from an account earning 4% average annual interest rate at the start of each year for 7 years, h
Ksju [112]

Answer:

Amount he must have in his account today is  $5,617.92

Step-by-step explanation:

Data provided in the question:

Regular withdraw amount = $900

Average annual interest rate, i = 4% = 0.04

Time, n = 7 years

Now,

Present Value = C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)

here,

C = Regular withdraw amount

Thus,

Present Value = C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)

Present Value = 900 \times\left[ \frac{1-(1+0.04)^{-7}}{ 0.04 } \right] \times(1 + 0.04)

Present Value = 936 \times\left[ \frac{1 - 1.04^{-7}}{ 0.04} \right]

Present Value = 936 \times\left[ \frac{1 - 0.759918}{ 0.04} \right]

Present Value = 936 × 6.00205

or

Present Value = $5,617.92

Hence,

Amount he must have in his account today is  $5,617.92

for example ,

dimension of room 1 = 5 x 3

dimension of room 2 = 2 x 3

dimension of room 3 = 4 x 5

area of room 1 = 15

area of room 2 = 6

area of room 3 = 20

total area = 15 + 6 + 20 = 41
