Answer:
530.66 square feet
Step-by-step explanation:
The formula for the area of a circle is :
The radius is also half of the diameter.
To work out the area you would simply multiply pi by the radius of 13 squared, this gives you 530.66 square feet. The radius is the length from the side of the circle to the centre.
This was calculated using 3.14 as pi.
1) Multiply pi by 13 squared.
Given:
The function is
This function is changed to f(x)+9.
To find:
The effect on the graph of the function.
Solution:
The translation is defined as
.... (1)
Where, b is vertical shift. If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The new function is
...(2)
From (1) and (2), we get
So, the graph of f(x) shifts 9 units up as shown in the below graph.
Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
Cos<span> 42° ~ 0.743
cos 42° = sin(90-42) = sin 58°
So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743
