Answer:
The approximate length of the diagonal walkway is 21.21 meters
Step-by-step explanation:
we know that
Applying the Pythagorean Theorem in the square park, find out the the approximate length of the diagonal walkway
so
where
c is the diagonal of the square
a and b are the length sides of the square
we have
substitute
therefore
The approximate length of the diagonal walkway is 21.21 meters
I think the answer is 126;
Answer:
The rate of change of each circular surface of the dough is approximately 150.796 in.²/minute
Step-by-step explanation:
The given parameters are;
When the radius of the dough, r = 12 inches, the radius is increasing at 2 inches per minute
Therefore, we have;
dr/dt = 2 in./min
The area of the circular surface of the dough, A = π·r²
The rate of change of each (top or bottom) circular surface area of the dough dA/dt is given as follows;
dA/dt = d(π·r²)/dt = π·2·r·dr/dt
Where;
r = 12 in.
dr/dt = 2 in./min
Substituting, we have;
dA/dt = π·2·r·dr/dt = π × 2 × 12 in. × 2 in./min ≈ 150.796 in.²/minute.
The rate of change of each circular surface of the dough = dA/dt ≈ 150.796 in.²/minute.
Answer:
Length of shadow = 49.07 feet
Step-by-step explanation:
We have given,
Height of building, AB = 25 feet
Length of shadow be BC.
Angle of the shadow opposite to the building = 27°
Using trigonometric function tan function
tan( 27 ) =
or BC =
or BC = 49.07 feet
So, length of shadow , BC = 49.07 feet
