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

An angle measures 162° less than the measure of its supplementary angle. What is the measure of each angle? ( i need two answers please help see the pic)
Answers
Answer:
[tex]9^\circ , 171^\circ[/tex]
Step-by-step explanation
If a represents the measure of the angle, then 180 - a is the measure of its supplement. (Supplements add up to 180 degrees.)
The sentence in the problem translates to an equation:
a = (180 - a) - 162
Simplify the right side.
a = 18 - a
Add a.
2a = 18
a = 9
The angle's measure is [tex]9^\circ[/tex]. The supplement is [tex]180^\circ - 9^\circ =171^\circ[/tex]

A sample of 100 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.239 and the equation of the regression line is y = 18.5 + 0.890x, where x represents height. The mean of the 100 heights is 62.9 in and the mean of the 100 pulse rates is 73.4 beats per minute. Find the best predicted pulse rate of a woman who is 65 in tall. Use a significance level of α=0.01 The best predicted pulse rate of a woman who is 65 in tall is_______beats per minute.. (Round to two decimal places as needed.) Answer
Answers
Answer:
54.07 inches
Step-by-step explanation:
Given the regression equation :
y = 18.5 + 0.890x
y = pulse rate in beats per minute
x = height
The best predicted pulse rate of a woman who is 65 inches
Put y = 65 in the regression equation :
65 = 18.5 + 0.890x
65 - 18.5 = 0.890x
46.5 = 0.890x
Divide both sides by 0.890
46.5 / 0.890 = 0.890x / 0.890
54.0697 = x
The best predicted pulse rate for a woman wo is 65 inches tall is 54.07 inches
