Answer:
On the scale 24 feet represents 62.06 feet.
Step-by-step explanation:
In the given scale:
14 inch represents 3 feet
Now, covert both the parameter into same length parameter.
1 inch = 0.08333 feet
⇒14 inch = 14 x 0.08333 = 1.16 feet
or, by conversion 14 inch = 1.16 ft
Hence, on the given scale, (14 inch = 1.16 ft ) represents 3 feet.
Let us assume that 24 feet represents k ft on the scale.
Then by RATIO OF PROPORTIONALITY:
Hence, on the scale 24 feet represents 62.06 feet.
We can solve for the arc length using the formula shown below:
Arc Lenght = 2pi*r(central angle/360)
We need to convert the central angle such as:
Central angle = 23pi rad * (180°/pi rad) = 23*180
Radius = 24cm
Solving for arc length:
Arc length = 2*3.14 *24*(23*180/360)
Arc length = 1733.28 cm
Answer:
4. 56 ft²
Step-by-step explanation:
SA = (4×4)+(4×½×4×5)
= 16+40
= 56
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change = 
= 
= - 4 → C
Answer:
A = 307.9 sq/cm
Step-by-step explanation:
Find the radius of the semi-circle
diameter + half the circumference = 72 cm
2r + pi*r = 72
r(2+pi) = 72
r = 72%2F%28%282%2Bpi%29%29
r = 14
:
what will be the area of that semicircle?
A =1%2F2*pi%2A14%5E2
A = 307.9 sq/cm
