Answer:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​

Step-by-step explanation:

Given that circumference of circle is: 24 \pi

The formula for circumference of circle is:

C = 2\pi r

Comparing both formulas, we get

24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12

The radius is obtained by dividing 24 by 2.

We also know that the area of circle is:

A = \pi r^2

The radius is being squared and then multiplied by pi to get the area.

Hence,

The correct answer is:

D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.​

Determine the standard form of the equation of the line that passes through (-6,6) and (3,-2)
Simora [160]

Answer:

y=(8/9)x + 4 and 2/3

Step-by-step explanation:

the slope of this line:

change in y/change in x

change in y=6-(-2)=8

change in x=-6-3=-9

change in y/change in x= 8/9

8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept

y=mx+b

y=(8/9)x+b

-2=(8/9)*3+b

-2=8/3+b

-4 and 2/3=b

slant height of a right cone is 5 inches, and radius of its base is 3 inches, what is the lateral area?
Alik [6]
*Hint: The formula for the lateral surface area of a right cone is LA= Πrs

All we have to do is plug in and solve.

LA= Π(3)(5)
LA = 15Π
LA = 47.1238898

The lateral surface area is around 48 inches.

The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in sec
kow [346]

Answer:

A) g(t) = - 16*t² + 80*t

B) domain is  ( 0 ≤ t ≤ 5 )

Step-by-step explanation:

A) for the model rocket

h = 0    and  v = 80 feet/sec

Then the equation     g(t)  = -16*t² + v*t + h

became

g(t) = - 16*t² + 80*t + 0         g(t) = - 16*t² + 80*t

B) The equation  g(t) = - 16*t² + 80*t  is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t)  then the biggest value for t = 5 from

-16*t²  +  80*t  ≥ 0

-16*t  ≥ -80       16*t ≤ 80

t ≤ 5

And the domain is  ( 0 ≤ t ≤ 5 )

Write an absolute value inequality and a compound inequality for each length x with the given tolerance.
BabaBlast [244]
<span>The absolute value inequality of a length of 36.80 mm with a tolerance of 0.05 mm</span> is given by |x - 36.80| < 0.05
and
The compound inequality of a length of 36.80 mm with a tolerance of 0.05 mm is obtained as follows:
|x - 36.80| < 0.05
-0.05 < x - 36.80 < 0.05
-0.05 + 36.80 < x < 0.05 + 36.80
36.75 < x < 36.85.
