Answer:

49π m² ≈ 154 m²

Step-by-step explanation:

The formula for the area of a circle is usually remembered as ...

A = πr² . . . . . for radius r

Here, we're given the diameter. We can either figure the radius from the diameter and use this formula, or we can rewrite the formula to use the diameter.

r = d/2 = (14 m)/2 = 7 m

A = π(7 m)² = 49π m² . . . . . "exact" answer

Sometimes when multiples of 7 are involved, we like to use π ≈ 22/7. Using that value, the area is ...

A = 49π m² = 49(22/7) m² = 154 m² . . . . . approximation using π = 22/7

Often, algebra problems insist on using the value π = 3.14. For that value, the area is ...

A = 49π m² = 49(3.14) m² = 153.86 m² . . . . . approximation using π = 3.14

Using the "pi button" on your calculator, the numeric answer is ...

A ≈ 49(3.14159265359) m² ≈ 153.938 m² . . . . using "pi button"

_____

If we rewrite the formula to use the diameter directly, then the area is ...

A = π(d/2)² = (π/4)d²

For the diameter of 14 m, this is ...

A = (π/4)(14 m²) = π(196/4) m² = 49π m² . . . . same as above

A rectangle has a length of 34 and an area of 2930, what is its width?

lara31 [8.8K]

You divide 2930 by 34 to get about 86.1765

Step-by-step explanation:

The measure of all the arcs can be obtained by using 'Central angle and its corresponding arc theorem'.

1. The measure of arc AD is $\boxed {105}\degree$

2. The measure of arc ABC is $\boxed {205}\degree$

3. The measure of arc ADB is $\boxed {190}\degree$

4. The measure of arc BD is $\boxed {85}\degree$

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34.

svet-max [94.6K]

Answer:

The sampling distribution of x is N(118, 2.5).

Step-by-step explanation:

We have that:

The mean of the population is $\mu = 118$

The standard deviation of the population is $\sigma = 25$ .

(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.)

The mean of the sampling distribution is the same as the mean of the population.

The standard deviation of the sampling distribution is the standard deviation of the population divided by the square root of the sample size. So

$s = \frac{25}{\sqrt{100}} = 2.5$

This means that the sampling distribution of x is N(118, 2.5).
