Answer:

The volume of the hemisphere is 496741.6 m³

Step-by-step explanation:

The volume of an sphere is given by:

V_{s} = \frac{4\pi r^{3}}{3}

In which \pi = 3.14 and r is the radius.

An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

V_{h} = \frac{V_{s}}{2} = \frac{2\pi r^{3}}{3}

In this question:

r = 61.9. So

V_{h} = \frac{2\pi (61.9)^{3}}{3} = 496741.6

The volume of the hemisphere is 496741.6 m³

Answer:

The volume of the hemisphere = 496741.6 m³

Step-by-step explanation:

Volume of a sphere is= (4/3) × π × r³

r is the radius

π is 22/7

hemisphere is half of an sphere,

so the volume of henisphere is  (2/3) × π × r³

Given that ;

r = 61.9 m

V = \frac{2\pi (61.9)^{3}}{3} = 496741.6

therefore, the volume of the hemisphere is 496741.6 m³

Determine whether or not the following question can be considered as a statistical question.
aleksandr82 [10.1K]

Answer:. No

Step-by-step explanation:

Explanation:

The answer is NO because, mostly, there is always a variability in

the data used in answering statisticall questions. As in the question above, no variability

because Megan is taller than Jim or she is not taller than jim.

Thus, the question is not statistical in nature.

In Melanie's Styling Salon, the time to complete a simple haircut is normally distributed with a mean of 25 minutes and a standa
Triss [41]

Answer:

Longer than 27.7 minutes.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 25, \sigma = 4

The slowest quarter of customers will require longer than how many minutes (to the nearest tenth) for a simple haircut?

Longer than the 100 - 25 = 75th percentile of times, which is X when Z has a pvalue of 0.75. So X when Z = 0.675. So

Z = \frac{X - \mu}{\sigma}

0.675 = \frac{X - 25}{4}

X - 25 = 4*0.675

X = 27.7

So

Longer than 27.7 minutes.

66inches long is to be cut into 5 1/2 inches pieces how many pieces can be cut
Goshia [24]
Each piece will be the same length.  We can convert 5 1/2 into an improper fraction.  5 1/2 = 11 / 2  Divide 66 by this improper fraction.  66 / (11 / 2)  When we divide by a fraction, we multiply by the reciprocal of that fraction. 66 * (2 / 11) = 2 * 6 = 12  12 pieces can be cut.
